Watermel Preserves

Ingredients

Directions

  1. Cut the watermelon rind into 2-inch pieces and soak in cold water.

  2. Add salt and alum to the rinds and let dissolve.

  3. Fill a kettle with cold water, add the rinds, and cover with a plate.

  4. Slowly bring to a boil and cook until easily pierced with a fork.

  5. Drain the rinds and prepare the syrup by boiling ginger in 2-3 pints of water.

  6. In another pan, boil the sliced lemons until tender.

  7. Make a syrup with sugar and the water used for boiling the lemons and ginger.

  8. Add the rinds and lemon slices to the syrup and boil slowly for 30-45 minutes.
