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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Minced cooked beef
- Forms the bulk of the croquette and gives it its savoury, meaty flavour.
- Onions
- Soften and sweeten as they fry, adding depth to the filling.
- All-purpose flour
- Thickens the stock into a sauce that binds the filling together.
- Beef stock or gravy
- Moistens the flour and adds beefy flavour and moisture to the filling.
- Egg whites
- Form a coating that helps the crumb-like flour dusting stick and brown.
- Butter
- Adds richness and promotes even browning in the frying pan.
The step that matters
Cook the filling until the sauce is dry. If the mixture stays wet, the croquettes will be too soft to hold their shape and may break or steam rather than brown in the pan.
Swap the onion
How well each one fits the dish's main ingredients (beef, butter, flour, pepper, nutmeg, parsley, egg):
