Why it works: Lettuce and celery match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 2,033 recipes. Both carry nonanal, which smells fat, citrus. The science ↓
Combination Salad
Ingredients
Directions
Prepare the vegetables
Select a nice head of lettuce; cut off the stalk and pull apart.
Wash and drain or wipe dry with a soft cloth; toss lightly on salad plates.
Cut the celery into very fine slices; form a ring of shredded celery on the lettuce.
Cut the tomato and green pepper into slices; place a slice of tomato and a ring of green pepper on each salad.
Make the dressing
For the dressing, mix paprika and salt in a bowl, add part of the oil and stir well.
Add vinegar and oil alternately until all are used.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Forms the crisp green base that holds the other salad components.
- Wesson oil
- Carries the dressing and adds richness and a smooth mouthfeel to the salad.
- Vinegar
- Adds acidity that brightens the dressing and balances the oil.
- Tomato
- Adds juiciness and a mild acidic sweetness to the salad.
The step that matters
Adding vinegar and oil alternately. Oil and vinegar do not mix on their own, so adding them in small alternating amounts while stirring helps form a more cohesive dressing that coats the leaves evenly instead of separating into layers.
