Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beef Croquettes
Ingredients
Directions
Prepare the filling
Chop the cold beef finely.
Soak the stale bread in hot stock, then add it to the chopped beef.
Mix in the beaten yolks of 2 eggs, pepper, salt, and onion juice.
Once the mixture is cool enough to handle, form it into croquettes.
Coat and fry
Roll each croquette in breadcrumbs, then dip in beaten eggs, and roll in breadcrumbs again.
Fry the croquettes in deep hot fat until golden brown.
Make the tomato sauce
For the tomato sauce, cook the tomatoes, onion, bay leaf, and parsley for 10 minutes.
Strain the mixture.
Melt the butter in a pan, add flour, and cook for 2 minutes.
Stir in the strained tomato mixture, season, and serve around the croquettes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Provides the bulk and savoury flavour of the filling.
- Eggs
- Yolks bind the filling and the whole eggs form a coating that helps breadcrumbs stick.
- Stale bread
- Soaked in stock, it absorbs liquid and keeps the filling moist and tender.
- Butter
- Fat that, cooked with flour, forms a roux to thicken the tomato sauce.
- Flour
- Thickens the tomato sauce when cooked with butter.
- Tomatoes
- Supply the acidity and body of the tomato sauce.
The step that matters
Fry the croquettes in deep hot fat until golden brown. Hot fat sears the breadcrumb coating quickly so it browns and seals before the filling overheats or the croquette absorbs grease. Fat that is too cool produces soggy, greasy coats.
Swap the onion

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