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 Peel
Ingredients
Directions
Prepare the rind
Soak grapefruit rind in cold salted water for 48 hours, changing the water 2 or 3 times.
Boil the rind in cold water, changing the water twice, until a straw can easily penetrate.
Remove the rind from heat and drain it.
When cool, cut the rind into strips.
Candy and store
Make a syrup with 1 cup of sugar and ⅓ cup of water for the rind of each grapefruit.
Add the strips to the syrup and cook until the syrup is fully absorbed.
When cool, roll each strip in granulated sugar and lay on a platter to dry.
Pack the candied strips in preserve glasses to keep them soft.

What each ingredient does
- Grapefruit rind
- Forms the chewy candied strips that absorb the sugar syrup.
- Sugar
- Sweetens the rind and, as syrup, replaces its water to make it candied and preserved.
- Coarse sea salt
- Softens and draws bitterness out of the rind during the long soak.
The step that matters
Boiling the rind in changed water. Boiling in several changes of water removes bitterness and softens the peel so a straw can pierce it. Skipping changes or boiling too briefly leaves the rind bitter or tough, which the later syrup cannot fix.
