As the summer sun turns to full blast, our thoughts veer toward cold treats. Rather than raid the icebox for some ice cream therapy, consider your options. Due to the demands of health conscious eaters, there's a growing list of alternative ingredients that make great substitutes for the eggs and milk typically found in ice cream. The general rule is this: if you can stick it in a blender and it freezes, then you can make treats. Try these variations on light and simple dairy: low-sugar, low-to-no fat frozen treats that can be made at home with no expensive equipment and a dash of ingenuity.
