Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Celery, Apple-and-green-pepper Salad
Ingredients
Directions
Prepare
Crisp the celery by soaking it in very cold water with lemon slices for 30 minutes.
Cut the celery into bits.
Peel and slice the apples, then cut them into cubes or small shapes.
Sprinkle the apple pieces with lemon juice to prevent discoloration and add flavor.
Scald the green pepper, remove seeds and veins, and cut it into fine shreds.
Assemble
Mix equal portions of apple and celery with the green pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides crisp texture and fresh, mild flavor to the salad.
- Apples
- Add crunch and natural sweetness that balances the savory vegetables.
- Green pepper
- Adds a slightly bitter, fresh bite and crisp texture.
- Lemon juice
- Adds acidity that brightens flavor and slows browning of cut apple.
The step that matters
Sprinkle the apple pieces with lemon juice. Cut apple browns quickly because its exposed flesh oxidises when it meets air. Acid from lemon juice slows this browning and keeps the apple pale, so it should be added right after cutting.
Swap the apple
How well each one fits the dish's main ingredients (celery, lemon, pepper):
- Limefits better
- Orangefits better
- Mangofits better
- Applethe original
Fit is the average pairing score against celery, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
