Cut the grapefruit peel in strips.

Place in a pan and cover with cold water. Bring to a boil. Drain. Repeat for a total of four times to remove the bitterness from the peel.

After boiling for the fourth time, place the peels back in the pan and top with 1/2 cup sugar.

Add just enough water to cover the peels and bring to a simmer. Simmer for 1 1/2 hours on low heat.

Place parchment or wax paper on a baking sheet and place a cooling rack on top.

Transfer the peels to the cooling rack and allow to dry overnight.

Toss with the remaining 1/4 cup of sugar.
