Boiled Cider for Apple Butter
Ingredients
Directions
Start boiling 10 gallons of sweet cider in a kettle.
As the cider reduces, add fresh cider until you have added 80 gallons.
Boil the cider until it reaches 215°F (100°C).
Once reduced to 1 part cider to 4 parts, add the apple pulp and sugar.
Cook the mixture until it thickens to your desired consistency.

What each ingredient does
- Sweet cider
- Reduces by evaporation to concentrate its sugars and flavor into a thick, spreadable butter.
- Fresh cider
- Added during reduction to bulk up the volume, adding apple flavor as the mixture concentrates.
- Apple pulp
- Provides body and apple solids that thicken the finished butter as it cooks down.
- Sugar
- Adds sweetness and helps the finished butter set to a spreadable texture.
The step that matters
Reducing the cider to 1 part cider to 4 parts. Adding the apple pulp and sugar too early leaves the mixture too thin and watery to thicken properly. Cooking down the cider first concentrates its sugars and flavor, so the final butter sets to the right consistency.
