Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Break down to add moisture and body, with mild acidity to the sauce.
- Apples
- Contain pectin, which helps the sauce thicken as it cooks.
- Raisins
- Add concentrated sweetness and a chewy texture to the sauce.
- Onions
- Soften and turn sweet as they cook, adding savory depth and aroma.
- Brown sugar
- Adds sweetness and balances the sharpness of the vinegar.
- Vinegar
- Adds acidity that gives the sauce its tang and helps preserve it.
The step that matters
Long boil of the mixture. Two to three hours of boiling evaporates water, thickening the sauce as its sugars concentrate. Sugar-rich mixtures can scorch on the bottom of the pot if the heat is too high or the sauce is left unattended.
