Sweetmeat Preserves

Ingredients

Directions

Prepare the rind

  1. Cut the rind into desired shapes.

  2. Soak the rind in brine until ready to make preserves.

  3. Dissolve alum in 1 gallon of water.

  4. Lay the rind in the alum solution, covered with grape or cabbage leaves.

  5. Simmer until the rind turns a pretty green.

  6. Soak the rind in soft water to remove alum.

Make the syrup

  1. Pour boiling water over the ginger.

  2. Let the ginger sit until soft enough to slice.

  3. Boil the ginger in ½ gallon of water for 1 hour.

  4. Add mace and 2 pounds of sugar to the ginger.

  5. Boil the rind gently in the syrup for 30 minutes.

  6. Add water to keep the rind covered.

  7. Set the kettle aside for 4 days.

Finish the preserves

  1. Boil again, adding 2 pounds of sugar and more water if needed.

  2. Repeat boiling 6 or 7 times until the syrup is rich and thick enough to cover the rind.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Watermelon rind
Forms the firm, sliceable body of the preserves that holds its shape in syrup.
Alum
Firms the rind's texture so it stays crisp through long boiling.
Sugar
Sweetens and, as the syrup thickens over repeated boils, preserves the rind.
White ginger
Adds a sharp, aromatic bite that flavours the syrup.

The step that matters

Removing the alum by soaking in soft water. Alum left in the rind can make it bitter and harsh, so it must be soaked out in soft water before the rind goes into the sugar syrup.

Swap the mace

How well each one fits the dish's main ingredients (egg, grape, ginger, sugar):

  1. Cinnamonfits better
  2. Cardamomfits better
  3. Nutmegfits better
  4. Macethe original

Fit is the average pairing score against egg, grape, ginger, sugar. Candidates are from the same food group and used in at least 100 recipes.
