Sometimes I get on kicks where I crave something and want it all the time. That happened the last time I was at Costco. It was a warm day, so I got a berry smoothie. That did it. I googled for the recipe and found one I adapted to my taste. But guess what? It can be made with all food storage ingredients!
I used yogurt as a base, maybe 1/2 cup, two packets of Stevia sweetner and about a 1/4 cup of water. I mixed it well in a blender and starting adding frozen blueberries and blackberries that I had bought on sale last summer. I blended and added till I got the taste and thickness I liked. That's it. I've found I add more blueberries to mine. It's a taste thing. Give it a try.
