Why it works: Endive and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 284 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Asparagus
Ingredients
Directions
Prepare
Soak the asparagus in cold water.
Cut the asparagus to remove the tough ends.
Chop the endive, lettuce, and onion finely.
Make the stew
Melt the butter in a saucepan.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Asparagus
- Forms the main body of the stew and adds its own vegetable flavour and texture.
- Butter
- Melted to cook the vegetables gently and carry flavour through the stew.
- Flour
- Sprinkled in to thicken the liquid and give the sauce body.
- Gravy
- Forms the stewing liquid, adding savoury flavour and moisture to the dish.
- Endive
- Chopped and stewed to add leafy texture and a slightly bitter note.
The step that matters
Sprinkle in the flour before adding the gravy. Flour needs to be cooked into the butter and vegetables before liquid is added, so it dissolves smoothly and thickens the sauce without lumps.
Swap the onion
How well each one fits the dish's main ingredients (asparagus, endive, lettuce, butter, pepper, flour):
- Beetrootfits better
- Chivefits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against asparagus, endive, lettuce, butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
