Why it works: Peas and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 4,887 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ingredients
Directions
Prepare
Shell the peas.
Boil a saucepan full of warm water.
Cook the peas
Once boiling, add the shelled peas, salt, and carbonate of soda.
Boil for 15 to 20 minutes, uncovered, until soft.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Provide the main body of the dish, softening during boiling to a tender texture.
- Butter
- Adds richness and a glossy coating that carries flavour across the peas.
- Carbonate of soda
- Raises the water's alkalinity, helping the peas soften more quickly and stay bright green.
- Castor sugar
- Adds gentle sweetness that balances the savoury salt and the vegetable flavour.
The step that matters
Tossing without frying. Tossing gently over heat for only a few minutes warms the peas through and lets the butter coat them. Longer or hotter cooking would brown the butter and toughen the peas.
Swap the peas
How well each one fits the dish's main ingredients (butter, sugar):
- Almondfits better
- Pecansfits better
- Filbertfits better
- Peasthe original
Fit is the average pairing score against butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
