Why it works: Pepper and lemon 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 ↓
Pepper Cocktail
Ingredients
Directions
Prepare
Cut off the stem end of the peppers and remove the seeds.
Soak the peppers in ice water until crisp.
Skin the tomatoes and dice them.
In a bowl, combine the diced tomatoes, Worcestershire sauce, soy sauce, lemon juice, and celery seed.
Serve
At serving time, place the peppers in small saucers filled with cracked ice.
Fill each pepper half with the tomato mixture, replace the top, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peppers
- Their crisp, hollow shells hold the filling and give the cocktail its crunch.
- Tomatoes
- They supply the bulk, moisture and tangy body of the savory filling.
- Worcestershire sauce
- Adds savory depth and a sharp, fermented note to the tomato mixture.
- Lemon juice
- Adds acidity that brightens the tomatoes and balances the savory flavours.
The step that matters
Soak the peppers in ice water until crisp. Cold water firms the cell walls of the pepper, so it stays crisp rather than limp once filled. Soaking long enough matters for a crunchy texture.
Swap the lemon
How well each one fits the dish's main ingredients (pepper, tomato, sauce, celery):
- Limefits about as well
- Lemonthe original
- Avocadofits about as well
- Cherryfits less well
Fit is the average pairing score against pepper, tomato, sauce, celery. Candidates are from the same food group and used in at least 100 recipes.
