Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Mock Sweetbread Croquettes
Ingredients
Directions
Prepare the brains
Remove membrane and blood vessels from the brains, wash well, and soak in salted water for 15 minutes.
Drain the brains, place them in a saucepan, cover with cold water, and bring to a boil.
Drain and cool the brains, then cut them into fine pieces.
Make the filling
In a saucepan, make a sauce with butter, flour, and milk, then add the brains and veal along with the seasonings, parsley, and onion juice.
Mix thoroughly and refrigerate until very cold.
Shape and fry
Shape the mixture into croquettes and fry according to general directions.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter 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
- Calf's brains
- Provide the soft, delicate meat that forms the body of the croquettes.
- Veal
- Adds meaty body and bulk to the filling.
- Flour
- Thickens the butter and milk into a sauce that binds the filling together.
- Butter
- Enriches the sauce and adds fat for a rich flavor and smooth texture.
- Milk
- Forms the liquid base of the sauce, adding moisture and creaminess.
The step that matters
Refrigerate until very cold. A thoroughly chilled mixture is firm enough to shape without slumping. Cold filling also helps the croquettes hold their shape when they hit the hot fat.
Swap the onion
How well each one fits the dish's main ingredients (veal, pepper, flour, parsley, butter, milk):
- Carrotfits better
- Shallotfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against veal, pepper, flour, parsley, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
