Why it works: Lettuce and watercress match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 307 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Cold Roast Fowl, a LA Mayonnaise
Ingredients
Directions
Roast and carve
Roast the fowl until cooked, then let it cool.
Cut the fowl into joints and stack them in the center of a serving dish.
Arrange the platter
Halve the lettuce and arrange it around the fowl as a border.
Wash the watercress and place it around the lettuce.
Cut the hard-boiled eggs in half or into rings and place them among the lettuce and watercress.
Serve
When ready to serve, cover the fowl with mayonnaise dressing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young fowl
- Provides the main cooked meat, which is firm and sliceable once roasted and cooled.
- Hard-boiled eggs
- Add firm, mild protein and a contrast of texture against the lettuce and meat.
- Lettuce
- Forms a crisp, cool border that contrasts with the rich dressed meat.
- Mayonnaise dressing
- Adds fat and creaminess, moistening the cold meat and giving a rich flavor.
The step that matters
Let the fowl cool before dressing. Mayonnaise is an emulsion of oil and egg that can break or turn greasy and thin when placed on warm meat. Cooling the fowl fully keeps the dressing thick and stable.
Swap the lettuce

Fit is the average pairing score against egg, watercress. Candidates are from the same food group and used in at least 100 recipes.
