Yield: 1/2 cup
Using a microplane zester/grater, freshly zest the grapefruit into a mixing bowl. Be careful not to include the white pith, as it has a more bitter flavor
Add the salt to the mixing bowl, and stir or whisk until incorporated with the zest. You may wish to put on gloves and use your hands. The freshly grated zest can be difficult to work throughout the salt with a spoon or whisk alone.
Next, add the sugar and ground chipotle and whisk to combine.
If you would like some more heat in the recipe, try a pinch of cayenne pepper or ground habanero pepper.
