Why it works: Pepper and celery match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Pepper and sugar barely smell alike, yet cooks put them together in 19,401 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides the crisp, fresh bulk and vegetal flavor of the relish.
- Red sweet peppers
- Add sweetness and color to the relish.
- Vinegar
- Adds acidity that gives the relish its sharp, tangy flavor and preserves it.
- Sugar
- Balances the acidity with sweetness and helps thicken the relish as it cooks.
The step that matters
Boil the mixture for 1½ hours. Long simmering softens the vegetables and lets the liquid reduce, so the relish becomes thick and the flavors blend. Stopping early leaves it watery and sharp.
Swap the celery
How well each one fits the dish's main ingredients (pepper, vinegar, sugar):
- Cinnamonfits better
- Tarragonfits better
- Allspicefits better
- Celerythe original
Fit is the average pairing score against pepper, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
