Apple Butter
Ingredients
Directions
Reduce the cider
Boil the cider until reduced to half its original quantity.
Cook the apples
Pare, core, and slice the apples to measure 2.5 bushels.
Add the apples to the cider and let them boil, stirring constantly.
Cook until the apples are reduced to a pulp, which will take 9 to 12 hours.
Continue boiling until the mixture is perfectly smooth and thick.
Avoid scorching the mixture to prevent spoilage.

What each ingredient does
- Cider
- Reduced by boiling to concentrate its flavor and form the liquid the apples cook in.
- Apples
- Break down into pulp that thickens the butter and gives it body as they cook.
The step that matters
Avoid scorching the mixture. Thick, sugar-rich fruit sticks and burns on the bottom of the pot during long cooking. Scorched sugars taste bitter and can spoil the whole batch, so stir constantly and keep the heat controlled.
