Why it works: Sugar and lemon are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 53,532 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Melon Marmalade
Ingredients
Directions
Prepare the rinds
Pare and weigh the watermelon rinds.
Soak the rinds in strong brine for a week.
Soak the rinds in water until they are fresh enough.
Boil the rinds in water until tender.
Make the marmalade
Combine ½ pound of white sugar with 1 pound of the rind.
Boil the mixture until it begins to thicken.
Add 1 box of dissolved gelatin to 12 pounds of marmalade.
Stir frequently and boil until you can slice it.
Flavor and finish
Once cold, flavor with lemon.

What each ingredient does
- Watermelon rinds
- Make up the bulk of the marmalade and give it a tender, chewy body.
- White sugar
- Adds sweetness and helps the mixture thicken as it boils.
- Gelatin
- Sets the marmalade so it holds a firm, sliceable shape when cold.
The step that matters
Boil until you can slice it. Stopping too early leaves the marmalade too soft to set, while boiling too long makes it stiff and tough. Stirring frequently keeps the sugar from scorching on the bottom of the pan.
