Why it works: Potato and onion 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 ↓
Curried Vegetables
Ingredients
Directions
Cook the vegetables
Cook the diced potatoes and carrots in boiling salted water until tender, then drain.
Combine
Add the green peas and curry sauce to the cooked vegetables.
Garnish

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk into a smooth sauce as its starch swells when heated.
- Milk
- Forms the creamy liquid base of the sauce, which thickens with the flour.
- Butter
- Carries the curry flavor and gives the sauce a rich, smooth mouthfeel.
- Curry powder
- Provides the main spiced aroma and flavor of the dish.
- Onion
- Softens and turns sweet and aromatic when cooked gently in butter.
- Potatoes
- Hold their shape while cooking and give the dish its starchy, tender body.
The step that matters
Adding the milk to the flour mixture. Pouring the milk in gradually while stirring constantly lets the flour disperse evenly, so the starch thickens the sauce smoothly instead of forming lumps.
Swap the peas
How well each one fits the dish's main ingredients (potato, carrot, sauce, butter, onion, flour, pepper):
- Beansfits better
- Chickpeafits better
- Lentilsfits better
- Peasthe original
Fit is the average pairing score against potato, carrot, sauce, butter, onion, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
