Can be served frozen or not, as either a salad or dessert. My cousin prepared this for me from a recipe she found, but hers used miniature marshmallows instead of cottage cheese. I like things less sweet, and more nourishing, so made the substitution. You can use different nuts than pecans - walnuts and hazelnuts are just as good (well, almost) in the recipe. I prefer it not quite frozen, but others like it best frozen.
