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 and Radishes
Ingredients
Directions
Prepare the lettuce
Wash each lettuce leaf separately and soak in cold water.
Set the lettuce on ice or in a cool cellar for at least an hour.
Dry the leaves with a soft towel and tear into pieces using a silver fork.
Make the dressing
For the dressing, mix equal parts lemon juice and sugar, diluted with a little ice water.
Alternatively, mix three or four tablespoons of thin cream with one teaspoon of sugar.
Add a little lemon juice to the cream if desired, just enough to thicken without curdling.
Arrange and serve
Wash the radishes thoroughly and arrange them in a glass dish with the ends meeting.
Scatter bits of cracked ice among the radishes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce leaves
- Form the crisp, leafy base of the salad.
- Young tender radishes
- Add crisp texture and a peppery bite to the salad.
- Thin cream
- Provides richness and a smooth, creamy body to the dressing.
- Lemon juice
- Adds acidity that brightens the dressing and, with cream, thickens it gently.
- Sugar
- Balances the acidity of the lemon juice with gentle sweetness.
The step that matters
Adding lemon juice to the cream. Acid can curdle cream if added too quickly or in excess. Adding only a little lemon juice and stopping once the cream thickens keeps the dressing smooth.
Swap the lemon
How well each one fits the dish's main ingredients (lettuce, sugar, cream, radish):
- Avocadofits better
- Limefits better
- Vanillafits about as well
- Lemonthe original
Fit is the average pairing score against lettuce, sugar, cream, radish. Candidates are from the same food group and used in at least 100 recipes.
