Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh peas
- Form the main body of the dish and become tender with gentle cooking.
- Unsalted butter
- Adds richness and moisture, coating the peas as they cook.
- Hearts of lettuce
- Soften as they cook and add moisture and a mild, sweet body to the peas.
The step that matters
Cook gently until the peas are tender. Low, gentle heat softens the peas evenly without browning the butter or toughening the skins. Stirring occasionally keeps the vegetables from scorching on the bottom of the pan.

- Clovethe original
Fit is the average pairing score against peas, butter, lettuce, parsley. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
