RASPBERRY-LIME SWIRL POPS

16 oz low-fat or non-fat vanilla yogurt

2 T fresh lime juice

8 oz fresh raspberries

4 T sugar

In a blender or food processor, puree yogurt and 1 tablespoon lime juice until smooth.  Transfer mixture to a bowl.  In the same blender/food processor, (no need to clean) puree the raspberries with the remaining lime juice and sugar.  Pass through a fine sieve to remove the seeds.  Pour the yogurt mixture and the berry puree in layers in 4 large popsicle molds or 8 oz cups.  Using a wooden popsicle stick, swirl the layers together.  Insert sticks, then freeze the pops for at least 6 hours or until they are solid.  To un-mold, run warm water over the bottom for a few seconds and gently pull.
