What each ingredient does
- Tripe
- Forms the main body of the dish, becoming tender after long, gentle simmering.
- Onions
- Soften during simmering, adding sweetness and mellow flavour to the milk and water.
- Milk
- Adds richness and creaminess to the cooking liquid, mellowing the tripe's strong flavour.
The step that matters
Simmer gently for 2.5 hours. A rapid boil toughens tripe and can curdle milk. Gentle simmering keeps the milk smooth and lets the tripe's connective tissue break down slowly until tender.
