Why it works: Lettuce and chestnut share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 64 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Cooked Lettuce
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the lettuce
Wash the lettuce heads in water with vinegar.
Cut the stalks close to the leaves.
Tie each head with tape or soft string.
Place each head in a wide saucepan.
Cover with boiling salted water.
Cook slowly without a lid until tender.
Carefully drain each head in a colander without bruising.
Remove the strings.
Place the lettuce in a hot dish.
Pour a nice milk sauce over the lettuce.
Make the macaroni and sauce
Boil the macaroni in salted water for 20 minutes.
Strain the macaroni.
Cool the macaroni in cold water.
Layer the macaroni in a dish.
Season with salt and pepper between layers.
Melt butter and flour in a saucepan.
Gradually add milk while stirring to prevent lumps.
Cook until boiling.
Season the sauce.
Bake in a moderate oven at 350°F (175°C) for 30 minutes.
Cook the chestnuts and sprouts
Boil chestnuts in cold water for 25 minutes.
Remove husks and skins from the chestnuts.
Cook Brussels sprouts in a little water and butter in a tightly covered saucepan.
Shake the Brussels sprouts occasionally.
Combine the chestnuts and sprouts.
Add a good piece of butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the main body of the dish, cooked until tender enough to hold its shape.
- Milk
- Forms the smooth sauce that coats and moistens the cooked lettuce.
- Macaroni
- Provides a starchy base layered in the dish, setting firm when baked.
- Butter
- Adds richness and fat, enriching the sauce and the vegetables.
- Flour
- Thickens the butter and milk into a smooth sauce.
- Chestnuts
- Adds starchy body and a mild, sweet, nutty flavour to the side dish.
The step that matters
Gradually add milk while stirring. Adding milk slowly while stirring lets the flour starch disperse evenly, so the sauce thickens smooth instead of lumpy.
