Why it works: Lettuce and endive 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, Fricasseed
Ingredients
Directions
Prepare
Wash the asparagus and cut off the tender portions.
Soak the asparagus in cold water until needed, then drain and chop it.
Chop the lettuce, endive, and onion.
Make the fricassee

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 dish and supplies its fresh, vegetal flavor.
- Butter
- Enriches the sauce with fat and adds a rich, round flavor.
- Flour
- Thickens the stock into a smooth sauce as it cooks.
- Stock
- Forms the liquid base of the sauce and carries the seasoning.
- Lettuce
- Softens as it stews, adding moisture and mild, sweet vegetable flavor.
- Onion
- Adds aromatic sweetness and depth to the stewed sauce.
The step that matters
Stirring the flour into the butter. Flour must be stirred until smooth before the stock is added gradually; adding liquid too fast can form lumps that are hard to remove, so the sauce will not thicken evenly.
Swap the onion
How well each one fits the dish's main ingredients (asparagus, lettuce, endive, butter, flour, pepper):
- Beetrootfits better
- Chivefits better
- Spinachfits better
