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 ↓
Lettuce, Stewed
Ingredients
Directions
Prepare the lettuce
Trim the outer leaves and bitter stalks from the lettuces and wash them carefully.
Boil the lettuces in plenty of salted water until tender.
Lift them into a colander, squeeze out the water, then chop slightly.
Make the stew
In a clean saucepan, combine the chopped lettuces with pepper, salt, and butter.
Dredge a little flour over the mixture and pour in the gravy.
Simmer gently for 15 minutes, stirring continuously.
Serve
Squeeze vinegar or lemon juice over the dish and serve hot with fried sippets.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuces
- Form the bulk of the dish and, once cooked, soften into a tender, spoonable texture.
- Butter
- Adds richness and a silky mouthfeel to the stewed lettuce.
- Flour
- Lightly thickens the gravy and liquid so the stew clings to the lettuce.
- Gravy
- Provides savoury, meaty flavour and the cooking liquid for the stew.
- Vinegar or lemon juice
- Adds acidity that brightens the rich, savoury stew just before serving.
The step that matters
Simmer gently while stirring. Flour thickens the gravy only as it heats, and it can settle and scorch on the pan base if the heat is high or stirring stops. Gentle, constant stirring keeps the sauce smooth and evenly thickened.
Swap the lettuce
How well each one fits the dish's main ingredients (pepper, butter, vinegar, flour):
- Shallotfits better
- Capsicumfits better
- Mustardfits better
- Lettucethe original
Fit is the average pairing score against pepper, butter, vinegar, flour. Candidates are from the same food group and used in at least 100 recipes.
