What each ingredient does
- Brains or sweetbreads
- Main protein; gentle simmering firms its delicate texture without toughening it.
- Vinegar
- Acidity that helps keep the meat pale and firm during simmering.
The step that matters
Bring to a boil, then reduce heat and cook slowly. Keeping the water at a gentle simmer rather than a hard boil helps the delicate brains or sweetbreads set firm and tender without breaking apart or becoming rubbery.
