Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Tripe
Its connective tissue becomes tender and yielding after long, gentle boiling.
Onions
Boiling softens them and their sweetness mellows into the sauce.
Butter
Melted fat carries the onion flavour and gives the sauce richness.
Flour
Starch thickens the milk into a smooth sauce as it cooks.
Milk
Forms the body of the sauce and adds mild sweetness and creaminess.

The step that matters

Boil the tripe until tender. Tripe is tough raw and needs long, gentle simmering so its connective tissue softens. Stopping early leaves it chewy, and a rolling boil can toughen the meat.

Swap the onion

How well each one fits the dish's main ingredients (milk, butter, flour):
