Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Meat Pie
Ingredients
Directions
Prepare the filling
Stew the meat in enough water to cover it until tender.
Line the sides of a pudding dish with rich crust.
Layer the stewed meat in the dish, seasoning well with salt, pepper, and onion.
Add a layer of sliced boiled potatoes and bits of butter.
Repeat layers until the dish is full.
Finish and bake
Pour the gravy from the stewed meat over the layers, thickened with a little flour.
Cover with a thick crust, leaving a slit in the middle.
If the pie gets dry, add more gravy or a little hot water.

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
- Meat
- Provides the main savoury filling, becoming tender through slow stewing in water.
- Flour
- Thickens the gravy so it coats the layers instead of running off.
- Butter
- Adds richness and moisture to the layers as it melts through the filling.
- Sliced boiled potatoes
- Adds body and starch that soaks up gravy, filling out the pie.
The step that matters
Thickening the gravy with flour. Flour must be cooked in the hot stewing liquid to thicken it evenly; added raw or in lumps it stays grainy and fails to bind the gravy.
Swap the onion
How well each one fits the dish's main ingredients (meat, pepper, potato, butter, flour):
- Chivefits better
- Shallotfits about as well
- Asparagusfits about as well
- Onionthe original
Fit is the average pairing score against meat, pepper, potato, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
