2 small boxes or 1 big box raspberry Jell-O (6-oz. total)
2 1/2 c. water, separated (see below)
1/3 c. frozen orange juice concentrate, still frozen
~20-oz. frozen raspberries, partially thawed
Pour 2 cups boiling water over the Jell-O powder (an 8x8-inch pan works nicely). Dissolve completely. Stir in frozen orange juice concentrate, swirling it around until melted. Stir in 1/2 cup cold water. Stir in raspberries. Refrigerate immediately and chill until set (it doesn't take as long as normal Jell-O since the berries and orange juice are so cold).
