Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Make up the fruit body of the preserve and hold their shape when handled gently.
- Sugar
- Adds sweetness and, dissolved into syrup, draws moisture from the fruit to help preserve it.
- Lemons
- Add acidity and a bright citrus aroma that balances the sweetness.
- Raisins
- Add concentrated sweetness and a chewy texture.
- White ginger-root
- Adds a warm, pungent aroma and a slight spicy bite.
The step that matters
Simmer until tender. Tomatoes are held in hot sugar syrup, and a hard boil can split their skins and turn the fruit mushy. A gentle simmer lets the fruit soften while it stays whole and holds its shape.
Swap the tomato
How well each one fits the dish's main ingredients (sugar, lemon, raisin, ginger):
- Arrowrootfits better
- Sweet potatofits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against sugar, lemon, raisin, ginger. Candidates are from the same food group and used in at least 100 recipes.
