Why it works: Cucumber and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,409 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Tomato and Cucumbeb Aspic
Ingredients
Directions
Make the tomato jelly
Cook down the can of tomato with the onion slice, salt, pepper, and parsley until smooth.
Strain the mixture, measure it, and set aside.
Dissolve 1 tablespoon of gelatin in ½ cup of water and mix it into the tomato mixture.
Mold and set
Rub a mold with a little oil and place thin slices of cucumber inside.
When the tomato jelly is cold, pour it into the mold or attach the cucumber slices with a little dissolved gelatin.
Let it firm up, then turn it out onto a bed of lettuce.
Garnish and serve
Garnish with overlapping cucumber slices and serve with stiff mayonnaise.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Gelatin
- Sets the tomato liquid into a firm jelly that holds its shape when turned out.
- Tomato
- Provides the main body, flavor, and color of the aspic.
- Cucumber
- Adds a cool, fresh flavor and a decorative pattern visible inside the jelly.
- Oil
- Lightly coats the mold so the set aspic releases cleanly.
The step that matters
Let the tomato jelly cool before pouring it into the mold. Gelatin sets only as the liquid cools. Pouring in hot tomato mixture can melt the thin cucumber slices out of place, and it may not set firmly.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, parsley, gelatin, cucumber, lettuce):
- Capsicumfits better
- Beetrootfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, parsley, gelatin, cucumber, lettuce. Candidates are from the same food group and used in at least 100 recipes.
