700gcooking liquid(homemade chicken stock plus Porcini rehydrating liquid)
100gheavy cream

Instructions
Instructions with the Thermomix:
Scale 10g of Porcini mushrooms, soak them in 1/2 cup of boiling water for 10 minutes, and retain liquid
Scale in the olive oil and add the onion and garlic; chop for 5 seconds at speed 7
Clean sides of bowl with the spatula; sauté for 2 minutes at 100°C on speed 5
Scale in chopped Cremini and sauté for 2 minutes at 100°C on R-4
Scale in chestnuts, reconstituted minced Porcini, strained Porcini water and chicken stock to total 700g liquid; cook for 10 minutes on Varoma at speed R-4
Purée for one minute slowly from 1-10, until smooth
Add cream, adjust seasoning and serve with a drizzle of truffle oil (2-3 drops per boil, as it is very strong)
Instructions without the Thermomix:
Weigh 10g of Porcini mushrooms, soak them in 1/2 cup of boiling water for 10 minutes, and retain liquid
Measure 2 tablespoons of olive oil into a stock pan and heat; add the chopped onion and garlic
Sauté for 2 minutes, stirring constantly; add the chopped Cremini and sauté for 2 minutes more minutes on high heat
Add chopped chestnuts, reconstituted minced Porcini, strained Porcini water and enough chicken stock to total 700g liquid; bring to a low boil and cook for 10 minutes
Test for doneness, then carefully move mixture to a blender: secure lid with a cloth over the top to avoid heat explosions or burns
Purée for one minute slowly, or until velvety smooth
Add cream, adjust seasoning and serve with a drizzle of truffle oil (2-3 drops per boil, as it is very strong)
Recipe Notes
Truffle Oils are always essences: the oil is flavoured artificially. Small Italian Artisan producers do infuse their own oil, but it is not available for export and tastes very different than the ones we pay so dearly for in Italy and at home.
