Why it works: Lettuce and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 4,037 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stewed Lettuces
Ingredients
Directions
Prepare
Remove the outer leaves and stalks from the lettuce.
Wash the lettuce thoroughly and soak it in salted water.
Cook and press
Cook the lettuce until tender, about 20 to 30 minutes.
Lift it out and press out excess water; chop it slightly.
Make the stew
In a clean saucepan, heat the chopped lettuce with pepper, salt, and a small slice of butter.
Sprinkle in a little flour and stir well.
Add a small cup of broth or gravy and boil until the mixture is fairly dry.
Stir in a little pale vinegar or lemon juice and serve hot, garnished with fried bread.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the bulk of the dish and becomes soft and tender when cooked.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the stewed mixture.
- Flour
- Thickens the cooking liquid so the stew becomes less watery and clings together.
- Broth or gravy
- Supplies the savoury cooking liquid that is reduced to flavour the lettuce.
- Pale vinegar or lemon juice
- Adds acidity that brightens the flavour and balances the richness.
The step that matters
Boil until fairly dry. Boiling after the broth is added lets water evaporate and the flour thicken the liquid. Stopping too early leaves the stew thin and watery, while boiling too long makes it dry and pasty.
Swap the lettuce
How well each one fits the dish's main ingredients (pepper, butter, flour, vinegar):
- Shallotfits better
- Capsicumfits better
- Mustardfits better
- Lettucethe original
Fit is the average pairing score against pepper, butter, flour, vinegar. Candidates are from the same food group and used in at least 100 recipes.
