Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Baked Tripe with Potatoes
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Braise the tripe
In a stew pot, combine tripe, onions, pepper, salt, and enough stock or water to cover.
Cook in a slow oven at 300°F (150°C) for 3 hours, adding more liquid if necessary.
Once tender, strain the gravy and remove any fat, then thicken it with flour until creamy.
Assemble and bake
Place the gravy and tripe in a pie dish and top with mashed potatoes.
Bake for 10 minutes or until the potatoes are hot throughout and browned on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Provides the main body of the dish, becoming tender through long, slow, moist cooking.
- Onions
- Soften during cooking and add sweetness and depth to the gravy.
- Flour
- Thickens the strained gravy so it becomes creamy and coats the tripe.
- Mashed potatoes
- Form the topping that browns in the oven while staying soft underneath.
The step that matters
Cook the tripe until fully tender. Tripe is tough connective tissue, and it only becomes tender after long, gentle cooking that slowly breaks down collagen. Rushing this step leaves it chewy, so it should be checked before the gravy is thickened and the dish is assembled.
Swap the onion
How well each one fits the dish's main ingredients (pepper, flour, potato):
- Chivefits better
- Spinachfits better
- Okrafits better
- Onionthe original
Fit is the average pairing score against pepper, flour, potato. Candidates are from the same food group and used in at least 100 recipes.
