Lettuce and Radishes

Ingredients

Directions

Prepare the lettuce

  1. Wash each lettuce leaf separately and soak in cold water.

  2. Set the lettuce on ice or in a cool cellar for at least an hour.

  3. Dry the leaves with a soft towel and tear into pieces using a silver fork.

Make the dressing

  1. For the dressing, mix equal parts lemon juice and sugar, diluted with a little ice water.

  2. Alternatively, mix three or four tablespoons of thin cream with one teaspoon of sugar.

  3. Add a little lemon juice to the cream if desired, just enough to thicken without curdling.

Arrange and serve

  1. Wash the radishes thoroughly and arrange them in a glass dish with the ends meeting.

  2. 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
