Why it works: Onion and lettuce match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and 3,562 recipes mention both. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
The recipe
Ingredients
Directions
Place the pulp of two oranges in the center of a cluster of crisp lettuce leaves.
Add one medium-sized Bermuda onion, sliced very thin.
Pour over this a French dressing that has sugar added.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oranges
- Adds juicy sweetness and bright acidity that balance the sharp onion.
- Bermuda onion
- Supplies a sharp, pungent bite that contrasts with the sweet oranges.
- Crisp lettuce leaves
- Forms the crisp base that holds the other ingredients and gives texture.
- French dressing
- Adds moisture, acidity and sweetness that coat the leaves and fruit.

- Onionthe original
Fit is the average pairing score against orange, lettuce, sugar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
