Why it works: Grapefruit and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 118 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Grape Fruit Salad
Ingredients
Directions
Prepare the fruit
Peel the grapefruit, divide into sections, and separate the membrane from the pulp.
Break the pulp into large pieces and place in a colander to drain into a dish.
Make the gelatin
Dissolve the lemon gelatin in boiling water and let it cool.
Add the juice from the grapefruit to the gelatin mixture.
Pour the mixture into a shallow pan and refrigerate until firm.
Cut the gelatin into 1-inch pieces and serve with the grapefruit sections.
Serve
Serve in the grapefruit shell or on a bed of head lettuce with a tablespoon of oil mayonnaise.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Grapefruit
- Provides the fresh fruit pieces and juice that add tartness and flavour to the salad.
- Lemon gelatin
- Sets the juice mixture into a firm, sliceable body that holds the salad together.
- Oil mayonnaise
- Adds richness and a creamy fat to the serving, softening the fruit's tartness.
The step that matters
Let the gelatin cool before adding the juice. Gelatin must be cooled to a warm, syrupy state before adding juice, because very hot liquid or an acidic juice added too early can weaken its setting and keep it from firming properly.
