Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Siberian crab apples
- Supply the fruit and natural pectin that help the preserve hold its shape and set.
- Refined sugar
- Sweetens the preserve, thickens the syrup and helps preserve the fruit.
- Orange peel
- Adds a citrus aroma and a bright flavour note to the syrup.
- Lemon peel
- Adds a fresh citrus aroma and a touch of brightness to the syrup.
The step that matters
Simmer the apples slowly until tender. Gentle heat softens the fruit while keeping the apples whole. Rapid boiling breaks the skins and flesh apart and can make the syrup cloudy.
Swap the apple
How well each one fits the dish's main ingredients (sugar, crab, orange, lemon):
