Before cooking sweetbreads, it is necessary to proceed with a few crucial steps:
First of all, it is necessary to disgorge it to remove the impurities and blood residues by letting it soak in cold water at least 4 to 12 hours. This will also prevent it from tasting too ferrous.
It must then be poached in a short broth for 3 to 4 minutes to facilitate the removal of the thin membrane that protects it.
Once the pieces are well drained and cooled, all that is left is to do is gently remove the membrane.
The sweetbreads are then ready to be cooked in all the possible ways!
