The Day Before:
1- Soak your veal sweetbreads for at least 3 hours in ice water, changing it every ½ hour.
2- In a pot filled with cold water add a few peppercorns a bay leaf a sprig of thyme and a pinch of coarse salt, then plunge your veal sweetbreads and after a good boil, drain them and refresh them in ice water, then remove them and place them on absorbent paper, continue carefully to degrease them and remove any remaining nerves, then place them on a plate on a cloth and install a second plate on top, and at the center place a 1 kg weight then into the fridge for 12h.
3- Prepare your duxelles:
In a sauté pan melt 50g of butter, then add your minced shallots, sweat gently for 5 to 6 minutes then add your mushroom duxelles salt and pepper with the mill when it starts to release its first water use a skimmer and press to collect this juice (which will be used in the glazing recipe) then place parchment paper over it with a hole in the center (chimney) and cook on very low heat for 30 minutes then remove your paper and dry it you can if you wish flame it with a little cognac (not mandatory) then set aside.
The Same Day:
