Why it works: Lettuce and radish share more aroma than cooks usually use. They rank in the top 2% of all ingredient pairs, and cooks put them together in 58 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Lettuce Salad
Ingredients
Directions
Prepare the lettuce
Select tender, fresh lettuce and dip it in cold water several times or soak for 10 minutes.
Carefully pick over the leaves and dry them with a clean towel.
Garnish and serve
Handle the leaves delicately and garnish with quartered hard-boiled eggs.
Serve with salt or your choice of dressing and accompany with radishes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the crisp, leafy base; soaking in cold water firms the leaves for a crunchy texture.
- Hard-boiled eggs
- Add soft, rich protein texture and a mild, savoury flavour to the salad.
- French dressing or mayonnaise
- Adds fat, acidity and flavour, coating the leaves and adding moisture.
- Radishes
- Contribute a sharp, peppery bite and a crisp crunch.
The step that matters
Dry the leaves thoroughly. Water left on the leaves dilutes the dressing and stops it clinging, so the salad turns watery. Dry leaves let the dressing coat them evenly and keep the texture crisp.
Swap the radish
How well each one fits the dish's main ingredients (lettuce, egg):
- Beetrootfits better
- Spinachfits better
- Chivefits better
- Radishthe original
Fit is the average pairing score against lettuce, egg. Candidates are from the same food group and used in at least 100 recipes.
