There’s a story about a tornado, wonky internet, wonky graphics cards (again!), and inertia, but nobody cares. On to the fruit!
Candied fruit is pretty straightforward – boil in water, boil in simple syrup, dry, sugar.
When I did these with orange peels, I shaved off some of the pith after the boil-in-water phase. The grapefruit peel was much thinner, so I didn’t bother.
After boiling in simple syrup – equal measures of water and sugar – for 45 minutes, the peels are translucent. And sticky.
After they’re sugared, they have to dry in open air for at least a day, two or three even better. Tap off the sugar and store in an airtight container.
