Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Mutton Croquettes with Tomato Sauce
Ingredients
Directions
Prepare the croquettes
Chop the cold mutton or other meats very fine.
Roll the crackers into fine crumbs and mix with the meat.
Season to taste and moisten with milk or water.
Mold the mixture into cakes and fry in butter until brown.
Make the tomato sauce
In a saucepan, combine the tomatoes, cloves, bay leaf, salt, white pepper, and onion.
Cover and simmer gently for 20 minutes.
In another saucepan, melt 2 tablespoons of butter with 2 tablespoons of flour over heat.
Gradually add the strained tomatoes, stirring until the sauce is smooth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold mutton or other meats
- Provides the main filling and savoury flavour of the croquettes.
- Crackers
- Fine crumbs bind the meat and give the croquettes body and structure.
- Milk or water
- Moistens the mixture so it holds together and stays tender when fried.
- Butter
- Fat that browns the outside of the croquettes and enriches the sauce.
- Flour
- Cooked with butter to form a roux that thickens the tomato sauce.
- Tomatoes
- Provide acidity and body as the base of the sauce.
The step that matters
Gradually add the strained tomatoes to the roux. Adding the liquid slowly while stirring keeps the flour smooth, so lumps do not form and the sauce thickens evenly.
Swap the white pepper
How well each one fits the dish's main ingredients (mutton, milk, butter, tomato, clove, onion, flour):
- Cinnamonfits better
- Cardamomfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against mutton, milk, butter, tomato, clove, onion, flour. Candidates are from the same food group and used in at least 100 recipes.
