Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Crab apples
- Provide the fruit that cooks until tender and carries the spiced flavor.
- Sugar
- Sweetens the syrup and helps preserve the fruit's shape and texture.
- Cider vinegar
- Adds acidity that gives the syrup its sharp balance against the sweetness.
- Stick cinnamon
- Infuses the syrup with warm, aromatic spice.
The step that matters
Cooking the apples in the syrup until tender. Cooking in a rich, hot syrup firms the skins and flesh so apples hold their shape, while overcooking makes them split and go mushy. Very ripe apples are softer, which is why the record offers steaming as an alternative.
