Ingredients

Directions

Prepare the rind

  1. Cut the watermelon rind into small pieces.

  2. Place the rind in a tub and sprinkle with salt.

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 bulk of the preserve and becomes tender and translucent after simmering in syrup.
Sugar
Forms the syrup that sweetens the rind and helps preserve it.
Salt
Draws water out of the rind during the initial marinating.
Lemon
Adds acidity and brightness that balances the sweetness of the syrup.
Ginger
Adds a warm, aromatic flavour to the syrup.

The step that matters

Simmering the rind until tender. The rind must be cooked gently until tender; simmering in syrup lets sugar slowly replace water in the tissue. Boiling hard can break the pieces apart and make the preserve cloudy and mushy.

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.
