Why it works: Grapefruit and sugar work together. They rank in the top 26% of all ingredient pairs, and cooks put them together in 309 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Candied Grapefruit
Ingredients
Directions
Prepare the peel
Remove the peel from the grapefruit in quarter sections and cut into strips ½ inch wide.
Weigh the peel and use an equal weight of sugar.
Cover the peel with cold water and let it stand overnight.
In the morning, simmer the peel in the water until very tender, about 5 to 6 hours, cooking very slowly.
Drain off the liquid.
Make the syrup and candy
If needed, add water to make the weight half that of the sugar.
Cook the sugar and water to a syrup.
Add the peel and simmer very slowly until the syrup thickens and the peel becomes clear.
Pick out the pieces of peel.
Dry and store
Roll them in granulated sugar.
Set on waxed paper to dry.
Store the candied grapefruit in tin containers.

What each ingredient does
- Grapefruit peel
- Provides the candied body that becomes tender and clear as it simmers in syrup.
- Sugar
- Sweetens the peel and, as syrup, replaces water in the peel to preserve it.
The step that matters
Simmering the peel until very tender. Peel left underdone stays tough and bitter, while overcooking can break it down. Slow simmering softens the pectin-rich membrane gradually so the strips become tender without falling apart before the syrup is added.
