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
Make the filling
Mince the cooked beef until you have 1 pint.
Season the beef with salt, pepper, grated onion, and lemon juice.
In a pan, mix butter and flour, then gradually add beef broth.
Stir in the seasoned beef and boil for 2 minutes.
Remove from heat and stir in the beaten egg thoroughly.
Pour the mixture onto a plate and let it cool.
Shape and fry
Once cool, shape 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
- Forms the bulk of the croquettes and provides the savory meaty flavor.
- Butter and flour
- Form a roux that thickens the beef broth into a binding base.
- Beef broth
- Adds moisture and savory flavor, and with the roux helps the mixture hold together.
- Beaten egg
- Sets when heated, binding the mixture so the croquettes keep their shape.
- Bread crumbs
- Form a crisp, golden browned outer coating when fried.
The step that matters
Let the mixture cool fully before shaping. A warm, soft mixture is sticky and hard to shape, and it can crack or fall apart in the coating. Cooling lets the starch and egg firm up so the croquettes hold their form during 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.
