I found this recipe from Crisco Oil in a very old Hadassah magazine stuffed in the back of a drawer in my grandmother's house. It's a favorite of mine. I think the nutmeg and lemon give the blueberries an exceptional flavor. I usually make it with milk (1 or 2%, but you can use water if you want to make it dairy-free. And if you can get them, try it with fresh blueberries. It is heavenly! (Although frozen work quite well, just taste for sweetness and adjust accordingly). These blintzes freeze very well, and I'll usually freeze them wrapped in packets of two. You can cook them up straight from the freezer; no thawing is needed. It's a really nice treat for kids with a dollop of sour cream, or even dusted with some powdered sugar, with or without cinnamon. They are surprisingly low in fat and calories.
