Watermel Rind Preserves
Ingredients
Directions
Prepare the rind
Line the bottom and sides of a kettle with vine leaves.
Layer watermelon rind and vine leaves, adding a small pinch of alum in each layer.
Cover with more leaves, a wet towel, and enough water to submerge the layers.
Simmer for 1 hour.
Remove the rind and place it on a dish.
Make the syrup
In a separate pot, combine 1 pound of sugar and 1 pint of water to make a syrup.
Once the scum has settled, add the rind and simmer for 30 minutes.
Remove the rind again and let the syrup simmer for 1 hour.
Return the rind to the syrup and simmer for another 30 minutes.
Let it stand overnight, then pour off the syrup.
Finish and jar
Boil the syrup until thick like honey and pour it over the rind in a jar.
Season with mace or ginger if desired.

What each ingredient does
- Watermelon rind
- Forms the bulk of the preserve and absorbs the sugar syrup as it cooks.
- Sugar
- Sweetens the preserve and, once thickened, gives it a syrupy body and preserving quality.
- Alum
- Helps the rind stay firm and crisp during long simmering.
- Vine leaves
- Lines and separates the layers so the rind cooks evenly without sticking to the kettle.
The step that matters
Boil the syrup until thick like honey. Reducing the syrup concentrates the sugar so it coats the rind and helps preserve it. Stopping too early leaves a thin, watery syrup that spoils more easily.
