- Cider
- Provides the liquid base and concentrated sweetness as it reduces.
- Cooking apples
- Break down during long cooking to form the thick, spreadable body.
The step that matters
Cook until soft, stirring constantly. Apple butter scorches easily on the bottom of the pan over long cooking. Constant stirring spreads heat evenly and prevents burnt flavour, while the slow reduction thickens the mixture.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
