Why it works: Tomato and onion are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 20,633 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tripe
- Forms the main body of the dish, giving a firm, chewy texture once cooked.
- Eggs
- Bind the cracker crumbs to the tripe so the coating holds during frying.
- Cracker crumbs
- Form a crisp, browned outer crust when fried.
- Tomatoes
- Add moisture and acidity that help break down and flavour the tripe.
- Onions
- Add savoury sweetness and aroma as they cook down with the tripe.
- Butter
- Adds richness and fat, carrying flavour through the dish.
The step that matters
Frying the coated tripe until golden brown. Frying at a steady heat browns the crumb coating through the Maillard reaction while keeping the tripe hot. Too low a heat soaks the coating with oil and leaves it greasy; too high a heat burns the crumbs before the inside is heated through.
Swap the tomato
How well each one fits the dish's main ingredients (onion, walnut, butter, egg):
