I bought this because I was intrigued by the large size and the thought of not worrying about the smoothie or popsicle mix overflowing as it was being immersion blended. Mission accomplished! This is a fantastic blending cup and then drinking cup. And a 9-ounce can of nuts, the plastic lid (under which is the peel-away metal lid) fits perfectly on this stainless steel container. Also, being that it's a non-reactive material, it's better for blending tomatoes and ginger and other such items as opposed to using anything plastic.
Smoothie: 1 cup NF plain yogurt, a splash or two of Naked, 100% Juice smoothie "Mighty Mango," a ripe peach and/or blueberries and/or strawberries. All fresh. Haven't tried frozen yet. Popsicles: see the great Mark Bittman's article [...] I like the creamy ones. Experiment with using less sugar, a teaspoon at a time. And don't cheap out on dollar store popsicle molds. Tovolo popsicle molds are great; find them here in amazon.
I see Amazon won't print a link. That's too bad. Just google Mark Bittman summer popsicles and it'll lead you to his summer ice pops article in NY Times Magazine.
