Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Red peppers
- Form the bulk of the sauce and break down into a soft pulp when boiled.
- Onions
- Add sweetness and body as they soften and mellow during long boiling.
- Garlic
- Contributes a pungent aroma that mellows and becomes savory with cooking.
- Wine vinegar
- Adds sharp acidity that brightens the sauce and helps preserve it.
- Horseradish
- Adds a sharp, pungent heat that gives the sauce its bite.
- Black pepper
- Adds a sharp, warming spice that rounds out the heat.
The step that matters
Cook the vegetables until very soft before straining. Peppers, onions and garlic must break down fully so the sieve can press them into a smooth pulp. Undercooked pieces stay fibrous and block the sieve, leaving a coarse, uneven sauce.
Swap the onion
How well each one fits the dish's main ingredients (pepper, garlic, horseradish, wine, vinegar, allspice, clove):
- Mustardfits better
- Shallotfits better
- Broccolifits better
