Why it works: Sauce and ketchup match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Meat Croquettes
Ingredients
Directions
Make the filling
Chop the meat finely.
Melt the butter in a pan, then add the flour and stock; stir until it boils.
Add the chopped meat, seasoning, and ketchup; mix well and transfer to a plate to cool.
Shape and coat
Once cool, form the mixture into rolls.
Dip each roll in beaten egg, then coat with breadcrumbs.
Fry and serve
Fry the croquettes in deep fat until golden brown.
Drain on paper and serve with seasoned gravy.

Butter and flour 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
- Scraps of meat
- Forms the main filling and provides the savory flavor of the croquettes.
- Flour
- Thickens the butter and stock into a binding sauce that holds the filling together.
- Butter
- Adds richness and fat, helping the flour mixture taste smooth and savory.
- Beaten egg (in the method)
- Acts as a sticky coating that helps the breadcrumbs adhere before frying.
The step that matters
Cool the filling fully before shaping. A warm, soft filling is too loose to hold its shape and can split or burst in hot fat. Cooling lets the starch-thickened mixture firm up so the rolls stay intact while frying.
Swap the parsley
How well each one fits the dish's main ingredients (meat, butter, flour, sauce, ketchup):
- Capersfits better
- Nutmegfits about as well
- Parsleythe original
- Tarragonfits about as well
Fit is the average pairing score against meat, butter, flour, sauce, ketchup. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
