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 ↓
Beef Croquettes
Ingredients
Directions
Prepare the beef
Mince the cooked beef until you have 1 pint.
Season the beef with salt, pepper, grated onion, and lemon juice.
Make the binding mixture
In a saucepan, melt the butter and mix in the flour.
Gradually add the beef broth, stirring until smooth.
Add the seasoned beef to the mixture and boil for 2 minutes.
Stir in the beaten egg thoroughly and pour the mixture onto a plate to cool.
Shape, coat and fry
Once cool, shape the mixture into croquettes, dip in egg, then coat with bread crumbs.
Fry the croquettes until golden brown and serve with tomato sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean cooked beef
- Provides the main filling and savoury flavour of the croquettes.
- Flour
- Thickens the butter and broth into a smooth mixture that holds the beef together.
- Butter
- Adds richness and fat, and helps form the initial roux with the flour.
- Beef broth
- Adds moisture and beefy flavour to the binding mixture.
- Beaten egg
- Binds the mixture and, as a coating, helps bread crumbs stick and brown.
- Bread crumbs
- Form a crisp, golden-brown outer crust when fried.
The step that matters
Cool the mixture before shaping. A warm, soft mixture is too loose to hold its shape and will slump or crack when dipped and coated. Cooling lets the starch-thickened binder firm up so the croquettes keep their form through frying.
Swap the onion
How well each one fits the dish's main ingredients (beef, pepper, lemon, butter, flour, egg, bread):
- Asparagusfits better
- Shallotfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against beef, pepper, lemon, butter, flour, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
