What each ingredient does
- Brains or sweetbreads
- The main ingredient; soaking and blanching firm up its delicate texture and make it easier to clean.
- Vinegar
- Adds a little acidity to the cooking water, which helps keep the meat pale and firm.
The step that matters
Bring to a boil, then cook slowly. Boiling hard toughens and breaks up delicate brains and sweetbreads. Holding the water at a gentle simmer for the stated five minutes keeps the texture tender and intact.
