What each ingredient does
- Cider
- Reduced by boiling to concentrate its flavor and sugars into the base of the butter.
- Sweet apples
- Break down during slow cooking to form the bulk of the smooth, sweet purée.
- Tart apples
- Add acidity and body, balancing the sweetness and helping the mixture thicken.
The step that matters
Cool slowly, stirring constantly. Sugar-rich mixtures scorch easily on the bottom of the pan and thicken unevenly. Constant stirring and gentle heat prevent burning and let the butter set to a smooth, spreadable texture.
