Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Pepper Sauce
Ingredients
Directions
Combine green peppers, onions, garlic, horseradish, cider vinegar, and water in a kettle.
Boil until soft enough to mash through a sieve with a spoon.
Pass all spices through a sieve before adding to the peppers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peppers
- Form the bulk of the sauce and soften into a mashable pulp when boiled.
- Onions
- Add body and savory sweetness as they soften into the sauce.
- Cider vinegar
- Provides acidity that gives the sauce its sharp flavor and helps preserve it.
- Horseradish
- Adds a sharp, pungent heat that fades somewhat with cooking.
The step that matters
Mash the peppers through a sieve while soft. Boiling until the peppers are fully soft lets them pass through the sieve smoothly. Under-cooked peppers stay fibrous and leave a coarse, uneven texture in the sauce.
Swap the mace
How well each one fits the dish's main ingredients (pepper, onion, garlic, horseradish, cider, vinegar, allspice):
- Thymefits better
- Clovefits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against pepper, onion, garlic, horseradish, cider, vinegar, allspice. Candidates are from the same food group and used in at least 100 recipes.
