Preserved Citron Melon

Ingredients

Directions

Prepare the melon

  1. Peel the melon, remove the inside, and cut it into thin strips, about ¼ inch thick.

  2. Weigh the melon and use the same weight in fine white sugar.

  3. Dissolve a little alum in water and boil the melon in it until tender.

  4. Place the melon on a dish, sprinkle sugar over it and between the pieces, and let it sit overnight.

Make the syrup

  1. Turn the syrup into a preserving kettle and boil until clarified.

  2. Add the melon to the syrup and boil until scalded through, then remove to cool on a dish.

  3. Add two lemons and a little preserved ginger to the syrup for flavor, then boil again until clear.

Jar and seal

  1. Pack the melon into jars and pour the syrup over it, ensuring it is not quite boiling hot.

  2. Seal the jars once cooled, as you would for other preserves.

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

Citron melon
Forms the firm, translucent strips that hold their shape after cooking in syrup.
Fine white sugar
Sweetens and, drawing moisture out overnight, preserves the melon as it becomes syrup.
Lemons
Add acidity and brightness that balance the sweetness of the syrup.
Preserved ginger
Adds warm, aromatic spice flavor to the syrup.

The step that matters

Boil the melon in alum water until tender. Alum firms the melon's cell structure so it keeps its shape through later boiling in syrup. Cooking until tender, without breaking the strips, sets the texture the rest of the process depends on.

Swap the melon

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

  1. Orangefits better
  2. Limefits better
  3. Mangofits better
  4. Melonthe original

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