Frozen Yogurt and Fruit Pops
Puree fruit in a blender and strain through a sieve.
Boil sugar with 4 tablespoons water until syrupy, then let cool. Mix syrup with fruit puree, lime juice, zest, and yogurt. Beat egg whites until stiff and fold into puree. Pour mixture into a shallow metal pan and freeze, stirring occasionally to prevent large ice crystals from forming.
When mixture is about half frozen, pour into cups, insert popsicle sticks and freeze 2-3 hours more.
