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 ↓

Ingredients
Directions
Make the curry
In a pan, brown the chopped onion in lard or butter.
Add curry powder mixed with a little water to form a paste and cook until fragrant.
Stir in the meat and add stock or boiling water to cover.
Let it simmer until the meat is tender.
To thicken the gravy, mix in the mashed potatoes.
For extra heat, add Worcestershire sauce.
Serve
Serve with boiled rice around the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Browned in fat first, it builds a sweet, savory base for the gravy.
- Curry powder
- Blooms in fat and a little water, releasing aroma and the dish's characteristic flavor.
- Meat of choice
- Becomes tender through slow simmering in stock, providing the main substance of the dish.
- Boiled potatoes
- Mashed into the liquid, they starch-thicken the gravy and add body.
The step that matters
Cooking the curry powder into a paste. Curry powder needs fat and a little moisture to bloom; cooking it briefly releases fat-soluble aroma compounds. Adding liquid too early or skipping this step leaves the spices raw and dusty-tasting.
Swap the onion
How well each one fits the dish's main ingredients (butter, meat, potato, sauce, rice):
- Asparagusfits about as well

Fit is the average pairing score against butter, meat, potato, sauce, rice. Candidates are from the same food group and used in at least 100 recipes.
