Blackberry Tie-Dye Pops

Place 7 1/2 ounces blackberries in the bowl of a food processor. Process until smooth, then pass through a fine sieve into a glass measuring cup. (You should have 1/2 cup puree.) Stir in 2 tablespoons lemon juice; set aside.

In the jar of a blender, blend yogurt with remaining tablespoon lemon juice until smooth.

Layer each 1/3-cup pop mold with yogurt and puree, adding the rest of the berries along the way. Swirl mixtures together with a knife.

Let freeze 25 minutes. Insert wooden pop sticks halfway, and freeze overnight.
