Why it works: Lettuce and butter are a kitchen classic. They rank in the top 25% of all ingredient pairs, and cooks put them together in 2,287 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Lettuce, Boiled
Ingredients
Directions
Prepare
Trim off the green outer leaves from the lettuce and wash the heart well.
Tie the lettuce heart with a piece of tape.
Boil
Place the taped lettuce heart in a saucepan of boiling salted water (1 tablespoon salt per quart of water).
Boil quickly until tender, about 20 to 30 minutes.
Carefully lift the lettuce out of the water.
Drain the lettuce well.
Remove the tape from the lettuce.
Serve
Cut the lettuce in half lengthwise and then across.
Lay the cut lettuce on a slice of buttered toast in a hot vegetable dish.
Pour melted butter sauce over the lettuce.
Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White cos lettuce
- Forms the body of the dish, becoming tender when boiled.
- Melted butter
- Adds richness and moisture over the cooked lettuce.
- Buttered toast
- Soaks up moisture and provides a base under the lettuce.
The step that matters
Drain the lettuce well. Water left in the leaves dilutes the melted butter and makes the buttered toast soggy under the lettuce.
