Why it works: Parsley and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Buttered Rice and Peas
Ingredients
Directions
Cook the rice
Combine the rice and water in a pot and bring to a gradual boil.
Boil hard for 5 minutes, stirring occasionally.
Reduce heat and move the pot to a cooler part of the stove or use an asbestos mat on a gas stove; allow the water to steam away until the rice is dry and cooked.
Add the peas and serve
Steam the peas in a separate pan for about 20 minutes, being careful not to overcook them.
Combine the cooked peas with the rice, adding the butter, parsley, and lemon juice.
Stir over low heat until the mixture is thoroughly hot.
Serve with or without tomato sauce and new potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Unpolished rice
- Forms the bulk of the dish and absorbs the cooking water to become tender.
- Fresh-shelled peas
- Add sweetness and a tender, bright green texture to the rice.
- Butter
- Adds richness and a smooth, fatty mouthfeel that coats the rice and peas.
- Lemon juice
- Adds acidity that brightens the flavour and balances the butter.
The step that matters
Steaming the peas. Peas turn dull, mushy and olive-coloured when overcooked, because prolonged heat breaks down their chlorophyll and soft cell structure. Stopping at tender keeps their colour and texture.
Swap the peas
How well each one fits the dish's main ingredients (rice, parsley, lemon, walnut, butter):
- Pistachiofits better
- Chickpeafits better
- Almondfits better
- Peasthe original
Fit is the average pairing score against rice, parsley, lemon, walnut, butter. Candidates are from the same food group and used in at least 100 recipes.
