Melon Preserve

Ingredients

Directions

Prepare the rind

  1. Cut the watermelon rind into small pieces.

  2. Sprinkle the rind with coarse sea salt, then cover it with cold water and let it marinate for 5 hours.

  3. Drain the rind.

  4. Soak the rind in cold water for 2 hours, changing the water 3 times.

  5. Drain the rind again.

  6. Place the rind in a preserving pan and cover it with boiling water.

  7. Bring the water to a boil.

  8. Drain the rind again.

Make the syrup and cook

  1. Make a syrup by boiling 10 lbs of sugar in 6 quarts of boiling water.

  2. Skim off any foam from the syrup.

  3. Add the rind to the syrup.

  4. Simmer the rind in the syrup until tender.

  5. Remove the rind from the syrup.

  6. Place the rind on draining sieves for 2 hours in a warm place to set.

  7. Once hardened, transfer the rind to cold crocks.

Finish with lemon and ginger

  1. Boil the syrup again with the lemon peel, juice, and sliced ginger for 10 minutes.

  2. Strain the syrup over the melon rind.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and ginger barely smell alike, yet cooks put them together in 14,054 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Watermelon rind
Forms the preserve's body, becoming tender and translucent as it cooks in syrup.
Coarse sea salt
Draws water out of the rind during marinating, firming its texture before cooking.
Sugar
Makes the syrup that preserves the rind and gives it sweetness and a set texture.
Lemons
Add acidity and brightness that balance the sweetness of the syrup.
Ginger
Adds warm, aromatic flavour to the syrup.

The step that matters

Simmer the rind until tender. Simmering slowly lets sugar gradually replace the water in the rind, so it becomes tender and clear rather than tough. Cooking too hard or too briefly leaves the texture uneven.

Swap the lemon

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

  1. Lemonthe original
  2. Orangefits about as well
  3. Limefits less well
  4. Vanillafits less well

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