Why it works: Parsley and lettuce match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,483 recipes. Both carry trans-2-hexenal, which smells green, leafy. The science ↓
Tomato Aspic Salad
Ingredients
Directions
Make the tomato base
Drain the liquid from the can of tomatoes and place it in a saucepan.
Add the bay leaf, onion juice, parsley, salt, and white pepper; bring to a boil.
Reduce heat and simmer for 20 minutes.
Set the aspic
Soak the gelatin in cold water for 5 minutes, then stir it into the tomato mixture.
Once the gelatin is dissolved, remove from heat and strain through a jelly bag.
Pour the mixture into a mold and refrigerate until set.
Serve
Once firm, turn out onto a platter and garnish with lettuce leaves.
Serve with mayonnaise dressing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the strained tomato liquid into a firm, sliceable aspic.
- Tomatoes
- Provide the main flavor and liquid base of the aspic.
The step that matters
Dissolving the gelatin before setting. Gelatin must fully dissolve into the hot tomato mixture and the mixture must be removed from heat first; if it boils or is left under-dissolved, the gelatin will not set evenly and the aspic can turn out weak or grainy.
Swap the white pepper
How well each one fits the dish's main ingredients (tomato, onion, parsley, gelatin, lettuce):
- Tarragonfits better
- Capersfits better
- Celeryfits better
- White pepperthe original
Fit is the average pairing score against tomato, onion, parsley, gelatin, lettuce. Candidates are from the same food group and used in at least 100 recipes.
