Recipe's preparation

    Sous vide fillet of beef
  1. Place the beef, beef fat and 2 of the thyme sprigs into a sealable vacuum bag and seal closed, according to the instructions on your vacuum sealer.
  2. Place water and lemon juice into mixing bowl and start Sous Vide/15 min/62°C.
  3. Place bag with beef into simmering basket. Insert simmering basket, ensuring bag is completely covered with water (water should be able to circulate around the bag) and start Sous Vide/15 min/62°C.
  4. Remove simmering basket with aid of spatula, then place bag with beef into a ThermoServer. Cover and set aside to rest for 5 minutes.
  5. Place a frying pan over high heat and add some oil. Remove beef from sealable bag, place into frying pan and sear on all sides for approx. 20 seconds, until browned on all sides.
  6. Add butter, garlic and remaining thyme sprig and continue to toss the beef through the butter for 1 minute, moving regularly. Remove from the pan, slice, garnish with thin potato chips (optional) and serve with Mushroom custard.
  7. Mushroom custard
  8. Place milk, mushrooms and thyme into mixing bowl and cook 25 min/80°C/speed 1.5. Strain mixture into a jug, then set aside to cool.
  9. Place a small bowl onto mixing bowl lid and weigh soy sauces into it. Add the eggs and whisk together. Then add to the infused milk and stir to combine.
  10. Pour mixture into a small, shallow dish (approx. 12 cm diameter) and carefully transfer into Varoma dish. Place water into mixing bowl, place Varoma with dish into position, secure Varoma lid and cook 12 min/Varoma/speed 2 or until set (custard should have the consistency and "wobble" of panna cotta). Cooking time may vary depending on thickness and shape of dish.
  11. Serve as desired.
  12. Jerusalem artichoke purée
  13. Place butter into mixing bowl and heat 2 min/90°C/speed 1, until bubbling.
  14. Add artichokes and thyme and cook 10-15 min/90°C/speed 1, until softened.
  15. Add just enough water (about 150 g) to cover artichokes and cook 15-20 min/100°C/speed 1, without measuring cup, until very soft and water has evaporated.
  16. Add cream and season with salt, then blend 30 sec/speed 4-8, increasing speed gradually from speed 4 to speed 8.
  17. Scrape down sides of mixing bowl with spatula, then blend for a further 30 sec/speed 4-8, increasing speed gradually from speed 4 to speed 8 until smooth. Serve as desired.


Ceps (also know as porcini mushrooms) can be found at gourmet food stores and some major supermarkets.

You can find white soy sauce at most Asian food stores.

Thermomix Model

  • Appliance TM 6 image
    Recipe is created for
    TM 6
    For cooking (simmering) at temperatures of 95°C or above (200°F), the simmering basket should always be used instead of the TM6 measuring cup, as the TM6 measuring cup fits tightly in the lid. The simmering basket rests loosely on top, is steam-permeable, and also prevents food spatter from the mixing bowl.
