Canned Watermelon

Ingredients

Directions

Prepare the rind

  1. Cut the rind of ripe watermelon into small pieces, removing all green parts.

  2. Boil the pieces until tender enough to pierce with a fork.

Make the syrup and can

  1. Make a syrup using ½ pound of sugar for every pound of fruit.

  2. Skim the melon from the pot and place it in the syrup with a few pieces of raw ginger.

  3. Cook for a few minutes, then put into cans and seal while hot.

What each ingredient does

Ripe watermelon
Forms the bulk of the preserve and softens into tender pieces when boiled.
White sugar
Sweetens the fruit and thickens the syrup, helping preserve it.
Ginger
Adds a warm, spicy aroma that contrasts with the sweet melon.

The step that matters

Sealing the cans while hot. Filling and sealing while the contents are hot drives out air, so a partial vacuum forms as the cans cool. This helps keep the preserve sealed and reduces spoilage.
