Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Fried Sweetbreads
Ingredients
Directions
Prepare the sweetbreads
Blanch the sweetbreads, press them, and cut into neat pieces.
Brush the pieces with beaten egg, roll in bread crumbs, and set aside for 10 minutes.
Repeat the egg and bread crumb process, then fry in boiling fat.
Make the sauce
Melt butter in a pan, stir in flour smoothly, and gradually add seasoning and milk.
Bring to a boil and cook for 3 minutes, then add cream and lemon juice.
Prepare the tomatoes and serve
Arrange the sweetbreads overlapping in the center of a dish and pour the sauce around them.
Prepare the tomatoes by covering them with boiling water for 2 minutes, then skin, slice, and cook gently in butter.
Place the cooked tomatoes in the center of the sweetbreads and garnish with fried croutons.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Main protein; blanching firms them so they can be cut into neat pieces and hold their shape when fried.
- Bread crumbs
- Form a crisp, golden coating on the sweetbreads when fried.
- Eggs
- Bind the bread crumb coating so it adheres to the sweetbreads.
- Flour
- Thickens the butter and milk into a smooth, cohesive white sauce.
- Milk
- Forms the liquid base of the sauce, giving it body and a mild richness.
- Butter
- Enriches the sauce with fat and flavor, and gently cooks the tomatoes.
The step that matters
Frying the coated sweetbreads. The fat must be boiling hot so the egg and crumb coating sets and browns quickly; cooler fat lets the coating soak up oil and fall away from the sweetbreads.
Swap the tomato
How well each one fits the dish's main ingredients (bread, pepper, egg, flour, milk, cream, lemon):
- Spinachfits better
- Asparagusfits better
- Arrowrootfits better
- Tomatothe original
Fit is the average pairing score against bread, pepper, egg, flour, milk, cream, lemon. Candidates are from the same food group and used in at least 100 recipes.
