Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the bulk and body of the sauce as they break down over time.
- Vinegar
- Adds acidity that preserves the sauce and gives it its sharp tang.
- Brown sugar
- Adds sweetness that balances the acidity and sharpness of the sauce.
- Cayenne pepper
- Provides heat, which intensifies as the sauce matures.
- Raisins
- Add sweetness and a soft, mellow body as they soften during the long steep.
- Garlic
- Adds pungent aroma that mellows and deepens during the long steep.
The step that matters
Keep the jar covered and stir daily for a month. The sealed jar and regular stirring let the acidic mixture steep evenly and mature without spoiling. Skipping the stirring can leave pockets of unmixed ingredients and uneven flavour.
Swap the raisin
