Why it works: Celery and pepper 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 ↓
Currant Jelly Sauce
Ingredients
Directions
Make the sauce
In a saucepan, melt the butter over medium heat and add the chopped onion. Cook until the onion begins to color.
Stir in the flour, bay leaf, and celery; cook until browned.
Add the stock and simmer for 20 minutes.
Strain the mixture and skim off any fat.
Return the strained sauce to the heat, add the currant jelly, and stir until melted.
Serve

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Butter
- Adds fat for richness and helps the onion brown gently.
- Onion
- Builds savory depth and flavor as it colors in the fat.
- Flour
- Thickens the sauce as it cooks with the fat and stock.
- Currant jelly
- Adds sweetness and fruity flavor, and sets the sauce to a glossy finish.
- Vinegar
- Adds acidity that brightens and balances the sweetness of the jelly.
- Stock
- Provides the liquid base that carries the savory flavor of the sauce.
The step that matters
Cooking the flour until browned. Flour must cook in the fat long enough to lose its raw taste and develop color; undercooked flour leaves a pasty flavor and dull, floury sauce.

Fit is the average pairing score against butter, onion, celery, vinegar, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
