BEFORE YOU START
Congratulations on purchasing the Thermomix TM31!
Before using your Thermomix TM31 for the first time, attend a demonstration with a qualified Thermomix advisor. Familiarize yourself with using your Thermomix TM31.
Before you start
Make sure to place your Thermomix TM31 on a clean, solid, and even surface so that it cannot slip. Keep your Thermomix TM31 in a permanent position in your kitchen so that you can operate it easily. Clean your Thermomix TM31 thoroughly before using it for the first time. Follow the instructions in the chapter on cleaning (page 36).
How to insert the mixing bowl correctly
Before inserting the mixing bowl, please always ensure that the speed selector has been set to
1. Insert the mixing bowl with the handle pointing to the front and push it gently into position 2 – the grooves on the sides of the bowl slide down the ridges on the shoulders of the appliance.
The mixing bowl has been inserted correctly if its handle is at the front, as shown in picture 2, and if the bowl itself is securely fixed in the appliance. To close the mixing bowl correctly, press the mixing bowl lid vertically onto the mixing bowl 3. The arrow must point to the handle of the TM31 bowl. Then turn the lid in a clockwise direction 4 times until you hear it “click” into place. Make sure to turn it all the way to the stop. Turn the speed selector to the closed lid position
; otherwise, the Thermomix TM31 cannot be switched on.
How to remove the mixing knife
To remove the mixing knife: hold the mixing bowl with one hand, with your other hand, turn the mixing bowl base 30 degrees clockwise, and pull the mixing bowl base downwards 5. Carefully hold the upper part of the mixing knife and remove it together with its sealing ring 6.
CAUTION: Danger of scalding by splashing hot food. Never try to open the mixing bowl lid by force. Only open the mixing bowl lid after the speed selector is pointing to the open lid position and the food or liquid in the TM bowl has stopped moving.
CAUTION: Danger of injury from a sharp mixing knife. Do not touch the blades of the mixing knife. They are very sharp. Hold the upper part of the mixing knife when removing or re-inserting it.
IMPORTANT: Take precautions to prevent the mixing knife from falling out accidentally.
How to insert the mixing knife
To re-insert the mixing knife, follow the ‘removal’ steps in reverse order. Put the mixing knife back into the mixing bowl 1 by pushing it through the opening in the bottom of the bowl 2.
Now, re-fit the mixing bowl base from below onto the mixing knife. Push the mixing knife through the opening in the bottom of the mixing bowl with one hand. With your other hand, hold the mixing bowl and turn (at the same time) the mixing bowl base 30 degrees counter-clockwise to lock 3.
ACCESSORIES
Before you start using your Thermomix TM31, we would like to present its accessories in more detail. They are proof of a well-thought-out design. Every part has been designed intelligently and serves several purposes.
Mixing bowl
On the inside and on the outside of the mixing bowl, there are marks indicating the filling level (4). Each mark corresponds to 0.5 liters. The mixing bowl has a maximum capacity of 2 liters (5).
CAUTION: Danger of scalding by splashing hot food. Place a maximum filling quantity of 2 liters of food and/or liquid into the mixing bowl. Observe the fill level marks of the mixing bowl.
Mixing bowl base
The mixing bowl base (6) is used to fasten and loosen the mixing knife within the mixing bowl. The whole mixing bowl may be placed on any work surface. There is no need to place a mat under the bowl.
IMPORTANT: The mixing bowl base must be turned as far as it will go and locked. Never place the bowl onto the appliance without first locking the mixing knife and mixing bowl base in place. Failure to fit the mixing bowl base and mixing knife correctly may result in damage to other parts of the Thermomix.
Mixing bowl lid
The mixing bowl lid is used to close the mixing bowl. For safety reasons, your Thermomix TM31 will not start working unless the lid has been positioned and locked correctly. Never try to force the lid open when the appliance is locked.
Take care to insert the sealing ring for the lid correctly. Put the lid upside down on your work surface and position the ring onto the lid by pushing it into the three hinges, whereupon you can hear a “click” (1). The sealing ring prevents liquid or food from escaping between the mixing bowl and the lid.
CAUTION: Danger of scalding by splashing hot food. Use Thermomix TM31 only with a correctly fitted, clean sealing ring of the mixing bowl lid. Inspect the sealing ring regularly. Should damage or leakage occur, replace immediately, at the latest every 2 years.
Measuring cup
CAUTION: Danger of scalding by splashing hot food.
- Be aware that single spots of hot food may escape from the opening of the mixing bowl lid. Place the measuring cup correctly into the opening, leaving it in place, especially when processing hot food (e.g., jam, soup) at medium (3–6) and higher (7–10, Turbo) speed levels.
- Do not cover the mixing bowl lid with towels or similar items.
- Always place the measuring cup correctly in the mixing bowl lid and ensure that it is not being pushed up by the contents of the simmering basket. If the hole in the mixing bowl lid is blocked with food and the heating is active, an overpressure can build up in the mixing bowl, and the hot contents might escape explosively. In this case, there is a high risk of burns and injuries.
The measuring cup is a multi-purpose item: it is a closing cap for the opening in the lid to avoid heat loss, and it prevents food to be mixed or cooked from escaping. The measuring cup can be used to measure ingredients. A measuring cup filled to the brim holds 100 ml, and a half-filled measuring cup (middle notch) holds 50 ml. Place the measuring cup into the opening in the lid with its opening showing upwards (2).
Only when using the butterfly whisk: position the measuring cup with the opening pointing downwards. If you wish to add some liquid, there is no need to remove the measuring cup. Simply pour the liquid onto the lid. It will gradually trickle into the mixing bowl. To add ingredients through the opening in the lid, lift the measuring cup and add them to the mixing bowl.
Simmering basket
The simmering basket for the Thermomix TM31 is made of high-quality plastic. Like the measuring cup, the basket is a multi-purpose item:
- Filtering of fruit and vegetable juices. Chop and make a puree in the Thermomix TM31, then insert the simmering basket into the mixing bowl and use it as a filter when pouring the juice out. When pouring the juice, use the spatula to hold the simmering basket (3).

- Delicate food, such as meatballs or fishballs, that are not suited to be prepared in the mixing bowl as a whole, should be put into the simmering basket. Here they can be stewed or steamed.
- For cooking side dishes (e.g., rice, potatoes). Removing the simmering basket is effortless: place the hook of the spatula into the notch of the simmering basket (4) and lift the basket (5). The spatula can be removed at any time.

- The feet at the bottom of the simmering basket (6) allow liquid to drip off the food in the basket.

- In case of reducing liquid in food (e.g., tomato sauce), put the simmering basket as a cover onto the lid (7) instead of the measuring cup.

CAUTION: Never overfill the simmering basket. Content must never protrude over the top rim of the simmering basket. Ensure that the hole in the mixing bowl lid remains free of food. If the hole in the mixing bowl lid is blocked with food and the heating is active, an overpressure can build up in the mixing bowl, and the hot contents might escape explosively. In this case, there is a high risk of burns and injuries.
Spatula
The spatula (1) is another example of the intelligent design of the Thermomix.
- The Thermomix TM31 spatula is the only instrument you may use to mix or stir the ingredients in the mixing bowl (2). Push it from above into the bowl through the opening in the lid. The safety disk ensures that the spatula is not caught by the mixing knife. This means that you can use the spatula during chopping, cooking, or simmering.

- The spatula should be used to scrape all ingredients from the mixing bowl. The tip of the spatula is shaped to fit exactly between the mixing knife assembly and the wall of the mixing bowl.
- The spatula has a specially shaped safety disk to make sure that it does not roll off the worktop.
- When filtering fruit or vegetable juices, use the spatula to hold the simmering basket in place.
- Removing the simmering basket is effortless with the spatula (see page 17, photo 4).
CAUTION
Danger of injury from the use of non-intended items.
- Use only the spatula with the safety disk (provided with the Thermomix TM31) for stirring food in the mixing bowl.
- Lock the mixing bowl lid before inserting the spatula through the opening in the mixing bowl lid.
- Never use other items such as spoons, cooking spoons, or any other tools for stirring. These might get caught by the rotating mixing knife, possibly resulting in injury.
Stirring attachment (butterfly)
- The butterfly (3) (here positioned on mixing knife 4) will help you to achieve the best results when whipping cream or beating egg whites. It is also the perfect utensil for the preparation of creamy puddings or cream mixtures.

- When boiling milk or preparing puddings or sauces, the butterfly allows a constant movement of ingredients. This will prevent the food from sticking. It is easy to insert and remove the butterfly: insert the butterfly as shown in picture (5). Its ball-shaped end ensures that it can be removed easily. To remove the butterfly, hold the ball-shaped end and pull it out with rotations in both directions.

CAUTION
- Only switch on the speed after the butterfly has been positioned in place.
- Do not select a speed higher than level 4 when the butterfly is fitted.
- Never use the spatula when the butterfly is fitted.
- Do not add ingredients that might damage or block the butterfly when the mixing knife is in motion and the butterfly is fitted.
Varoma
The Varoma (1) consists of three parts (2):
- Varoma dish (bottom)
- Varoma tray (middle)
- Varoma lid (top)
All parts are made of high-quality, food-compatible plastic.
NOTICE
- Always store the Varoma with its lid closed (1).
- Use Varoma only with Thermomix TM31 (not suitable for microwave, oven, or other appliances).
How to combine the Varoma parts
You can use your Varoma in either of the following two combinations:
- Combination 1: Varoma dish plus Varoma tray and lid (2). Use this combination for cooking different foods, e.g., vegetables with meat or fish, or a larger amount of the same food, e.g., yeast dumplings.
- Combination 2: Varoma dish plus Varoma lid (3). Use this combination for cooking large amounts of the same food, e.g., vegetables, potatoes, or large pieces of meat or sausages.

CAUTION: Danger of scalding by hot steam and hot condensed water. Never use Varoma without the Varoma lid.
IMPORTANT: If the Varoma lid is not positioned properly, the steam will escape, and the food inside the Varoma will not cook properly.
How to use the Varoma correctly
Your Varoma is an accessory designed for the Thermomix TM31 and can only be used with the TM31. Before you can start steam cooking with the Varoma, you will need to set up your Thermomix TM31 correctly.
Step 1: Set up Thermomix TM31.
Place the mixing bowl into position. Pour at least 0.5 liter (500 g) of water into the mixing bowl for up to 30 minutes of steam cooking. If you steam cook with a simmering basket, insert the simmering basket and fill it with ingredients, e.g., potatoes or rice. Close the mixing bowl with the mixing bowl lid and lock it. For a flavorsome variation, you can use a vegetable broth or a water-wine mix instead of water.
Step 2: Filling the Varoma.
Place the Varoma lid upside down on your work surface (4) and position the Varoma dish on top – it fits precisely into the groove. Now loosely fill the Varoma dish with food (5). Make sure that some slots remain open so that the steam can spread evenly. As you fill the Varoma, put food requiring longer cooking at the bottom, and food requiring shorter cooking at the top. The Varoma lid underneath the Varoma dish will stop the liquid from washing vegetables, ripe fruit, raw meat, or fish from wetting your work surface.
CAUTION
Danger of scalding by hot steam and hot condensed water.
- Ensure that the opening of the mixing bowl lid and some slots of the Varoma dish and tray remain free; otherwise, there can be uncontrolled escape of steam.
- Be sure to position the Varoma correctly onto the mixing bowl and appliance.
When using the Varoma tray, insert it into the Varoma dish. Make sure the Varoma tray is positioned loosely and evenly. Then place food onto it (1). Place the Varoma upright into position onto the locked mixing bowl lid (without the measuring cup) in such a way that it sits well (2). Place the Varoma lid on top. It should be positioned loosely and evenly so that it seals the Varoma well, allowing no steam to escape.
IMPORTANT: Never leave the measuring cup in the mixing bowl lid when using the Varoma. If the Varoma lid is not positioned properly, not enough steam will stay in the Varoma. This will slow down the cooking process.
CAUTION
Danger of scalding by hot steam and hot condensed water.
- Mind hot steam escapes at the sides and from the top of the Varoma lid during operation.
- Keep children away from THE Thermomix TM31 when using the Varoma and warn them about the danger of hot steam and hot condensed water.
Danger of scalding by splashing hot food.
- Use only low speed levels
when selecting Varoma temperature. Higher speed levels can lead to splashing hot food or liquid to froth up.
Step 3: Steam cooking with Varoma (3).
All you need to do is select the time and Varoma temperature on the control panel. The steam cooking process begins when you turn the speed selector to a low speed setting
. The timer starts to count down. Water or water-based liquid in the mixing bowl heats up to over 100°C, developing hot steam. The steam rises through the opening in the mixing bowl lid of the Thermomix TM31 into the Varoma. The food is cooked gently in the hot steam. Please note that the maximum Varoma temperature is 120°C, depending on what ingredients you are using, e.g., oil.
When the ingredients are cooked or if you want to check whether they are cooked, turn the speed selector to closed or open lid position
. In order to open the Varoma, slightly incline the Varoma lid carefully to the front so that the steam can escape on the back 4. Take care to let the condensation water drip into the Varoma dish and tray by holding the Varoma lid above them. Then carefully remove the Varoma lid and place it upside down onto the work surface. Lift the Varoma dish and tray up, wait a few seconds so that the condensed water drips onto the mixing bowl lid. Then place the Varoma dish and tray onto the Varoma lid.
Practical work with the Varoma
This description explains clearly how easy it is to use the Varoma. Observe the following basic rules for using the Varoma:
- Place enough water in the mixing bowl.
- The bottom of the Varoma dish and tray are both designed with an even pattern of small slots to guarantee an even distribution of steam in the Varoma. The food should always be positioned so that as many slots as possible remain “free.” Lying the food in “loosely” is usually enough to ensure this.
- You can cook foods of different consistencies and hardness at the same time. Place food requiring longer cooking at the bottom and food requiring less cooking at the top, e.g., vegetables in the Varoma dish and fish on the Varoma tray.
- The vegetables will be evenly cooked if you cut them into similar-sized pieces. The cooking times stated are approximate. Cooking time varies depending on the quality, ripeness, and size of the ingredients, as well as your personal preferences.
- Grease the Varoma dish and tray to make sure that ingredients such as meat, fish, or dough do not stick.
- Do not thicken your sauces and soups until the steam cooking process is finished. Thickeners may stop steam from forming evenly in the mixing bowl and slow down the overall cooking process.
- You can also turn the Varoma lid upside down and use it as a drip collector for the Varoma dish and the Varoma tray 1. It can also be used as a tray to serve food directly from the Varoma.
