Why it works: Lemon and pepper 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 ↓
Creamed Sweetbreads
Ingredients
Directions
Prepare the sweetbreads
Remove pipes and membranes from the sweetbreads.
Cook sweetbreads in boiling salted water with 1 tablespoon lemon juice for 20 minutes.
Plunge sweetbreads into cold water to harden.
Cut sweetbreads into small pieces.
Make the sauce
Heat 1 pint of milk in a saucepan.
Beat the yolks of 3 eggs and add a little cold milk.
Strain the egg mixture into the warm milk and cook over hot water until the sauce thickens.
Add 1 tablespoon butter, 1 tablespoon flour, salt, and pepper to taste, stirring constantly until smooth and thick.
Pour the sauce over the sweetbreads.
Bake
Place in a baking dish, shells, or paper cases.
Cover with bread crumbs and bake until brown.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweetbreads
- Form the main body of the dish, becoming tender when simmered and then cut into pieces.
- Egg yolks
- Thicken the milk into a smooth, rich sauce that sets as it cooks.
- Milk
- Forms the liquid base of the sauce, which thickens with the egg yolks.
- Flour
- Thickens the sauce and gives it a smooth, stable body.
- Butter
- Adds richness and smoothness to the sauce.
- Bread crumbs
- Form a crisp, browned topping when baked.
The step that matters
Cooking the egg yolk sauce over hot water. Egg yolks thicken when heated gently; too much heat curdles them into a grainy texture. Cooking over hot water and stirring keeps the sauce smooth and thick.
Swap the lemon

Fit is the average pairing score against milk, egg, butter, flour, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
