Why it works: Pepper and tomato are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 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
- Eggs
- Bind the batter and help the crumb coating cling to the sweetbreads.
- Flour
- Thickens the egg batter so it coats the sweetbreads evenly.
- Cracker dust or dry bread crumbs
- Forms a crisp outer crust that browns during frying.
- Sweetbreads
- The main protein, which becomes tender inside while the coating crisps.
The step that matters
Frying in hot lard until golden brown. If the lard is not hot enough, the coating absorbs fat and turns greasy instead of crisp. Too hot, and it browns before the inside is cooked through.
Swap the tomato
How well each one fits the dish's main ingredients (egg, flour, pepper, bread, sauce):
- Shallotfits better
- Capsicumfits better
- Spinachfits better
- Tomatothe original
Fit is the average pairing score against egg, flour, pepper, bread, sauce. Candidates are from the same food group and used in at least 100 recipes.
