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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Softens as it boils, adding mild sweetness and a savory base to the liquid.
- Milk
- Adds richness and body, making the sauce smoother and creamier.
- Crushed crackers
- Their starch swells in hot liquid and thickens the sauce.
- Celery extract
- Provides the main celery flavor and aroma.
The step that matters
Thicken with crushed crackers and boil for 15 minutes. Starch from the crackers only thickens fully once it is heated, and it can clump if added all at once. Boiling for the full time lets the starch swell evenly so the sauce sets to the intended consistency.
Swap the onion
How well each one fits the dish's main ingredients (pepper, milk, celery):
- Carrotfits better
- Capsicumfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against pepper, milk, celery. Candidates are from the same food group and used in at least 100 recipes.
