1/2 cup clear crystal sugar, white sparkling sugar or sanding sugar (see Tips), divided
1 teaspoon frozen (thawed) cranberry, orange or Concord grape juice concentrate or natural liquid dye (see Tips)
Place sugar in a small bowl. Stir in juice concentrate (or dye) until evenly blended. Adjust color with more additions as desired.
Spread the colored sugar in a thin layer on a small parchment-lined baking sheet. Turn on the oven to 350 °F for 2 minutes, then immediately turn it off. (The warm oven dries the sugar, but too much heat will burn it.) Let the sugar stand in the oven for 1 1/2 hours.
Make Ahead Tip: Refrigerate colored sugar airtight for up to 1 year.
Find clear (or white) sanding sugar (aka sparkling or coarse sugar) in well-stocked baking stores, gourmet food shops or online at kingarthurflour.com.
