Use a hickory stick for stirring.

What each ingredient does
- Sweet cider
- Reduces down to concentrate its sugars and flavor, forming the base of the marmalade.
- Apples
- Provide pectin and body, and their fruit solids thicken the reduced cider as it cooks.
The step that matters
Stirring during the long boil. Constant stirring keeps the thickening mixture from scorching on the bottom of the kettle, since sugars caramelize and burn once concentrated and hot.
