Why it works: Lettuce and beetroot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 678 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓
Crab Salad
Ingredients
Directions
Prepare
Remove the meat from the crab shell and shred it finely.
Wash and dry the lettuce, then break or cut it into small pieces.
Wash and pick the watercress, breaking it into small pieces.
Slice the tomato thinly.
Dress and serve
In a bowl, mix the salad oil, vinegar, salt, and pepper.
Add the lettuce, watercress, and stir lightly until mixed.
Fold in the crab meat and mix well.
Garnish with slices of beetroot, tomato, and the hard-boiled egg, which should be rubbed through a wire sieve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crab
- Provides the main protein and flesh that gives the salad its substance.
- Hard-boiled egg
- Rubbed through a sieve, it adds a soft, rich garnish and creamy texture.
- Salad oil
- Carries fat and flavour into the dressing and coats the leaves.
- Vinegar
- Adds acidity that brightens the dressing and balances the oil.
- Lettuce
- Forms the crisp, watery base that gives the salad its fresh texture.
The step that matters
Dress the leaves lightly. Stirring the lettuce and watercress gently keeps them from bruising and wilting. Dressing just before serving preserves their crispness, since the acid and salt in the dressing draw water out of delicate leaves over time.
