Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Meat and Macaroni
Ingredients
Directions
Prepare
Cook the macaroni in boiling water until tender, then cut into short lengths and keep hot.
Remove jelly or gristle from the meat, and place it with any bones or trimmings in a saucepan with 1 ½ cups cold water.
Simmer for at least 1 hour.
Cut the meat into small slices and the onion into dice.
Make the gravy
Melt the butter in a pan, add the onion, and cook until brown.
Sprinkle in the flour and cook for about 10 minutes.
Add the gravy and sauce, stirring until boiling.
Serve
Add the meat, baste well with the gravy, and serve on a dish with the macaroni arranged as a border.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tinned meat
- Provides the main body of the dish, and its bones and trimmings add flavour to the stock.
- Macaroni
- Forms the starchy base and border that holds the dish together on the plate.
- Flour
- Thickens the butter and onion mixture so the gravy becomes smooth and clings to the meat.
- Butter or dripping
- Carries the onion and gives the gravy a rich, savoury fat base.
- Stock or gravy
- Supplies the liquid for the sauce, adding savoury depth and moisture.
The step that matters
Cooking the flour. Cooking the flour in fat for a full ten minutes drives off its raw, pasty taste and lets it thicken evenly. Stirring in the liquid too early or too quickly can leave lumps.
Swap the onion
How well each one fits the dish's main ingredients (meat, butter, flour, ketchup):
- Shallotfits better
- Leekfits better
- Turnipfits about as well
- Onionthe original
Fit is the average pairing score against meat, butter, flour, ketchup. Candidates are from the same food group and used in at least 100 recipes.
