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 ↓
Chicken Croquettes
Ingredients
Directions
Make the filling
In a saucepan, blend the butter and flour.
Slowly add the milk or stock and bring to a boil.
Combine the mixture with the minced chicken to form a stiff paste.
Add a pinch of mace, salt, and pepper, then let it cool.
Shape and fry
Roll out the pastry very thin and cut out as many rounds as possible.
Brush the edges of each round with beaten egg and place a good teaspoonful of the chicken mixture in the center.
Fold the pastry over and pinch the edges to seal.
Coat with egg and breadcrumbs.
Fry in hot oil until light brown.

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
- Butter and flour
- Form a roux that thickens the milk or stock into a smooth sauce binding the filling.
- Milk or stock
- Provides the liquid that, thickened with the roux, makes the filling moist and cohesive.
- Minced chicken
- Provides the main filling, which the thickened sauce holds together as a stiff paste.
- Egg
- Seals the pastry edges when brushed on and gives the coating a golden browning before frying.
- Pastry
- Forms a thin outer shell that encloses the filling and crisps when fried.
The step that matters
Cool the filling until stiff before shaping. A warm, loose filling softens the pastry and can burst or leak during folding and frying. Cooling lets the starch-thickened sauce set so the filling holds its shape.
Swap the mace
How well each one fits the dish's main ingredients (chicken, milk, butter, flour, egg, pepper):
- Nutmegfits better
- Parsleyfits better
- Cinnamonfits better
- Macethe original
Fit is the average pairing score against chicken, milk, butter, flour, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
