What each ingredient does
- Tripe
- Main protein; long simmering in liquid softens its chewy texture.
- Milk
- Adds a mild, creamy richness to the cooking liquid.
- Onions
- Soften and turn sweet as they cook, providing flavor for the sauce.
The step that matters
Add onions at least 30 minutes before the tripe is done. Onions need a long, gentle simmer to become tender and sweet. If added too late, they stay firm and sharp, which weakens the flavor of the sauce.
