Mr. ETB brought home some fancy grape juice last week, and as we had seltzer water, and some homemade ice cream, we made Purple Cows. You could do this with grape soda, which I think is the correct way, but since when do I do anything the, "correct" way? That's right. Enjoy your purple cow.
The only instruction I have is to chill the glasses in the freezer first. How long? I dunno, I lost track-maybe the time it took to play four rounds of Boggle? Yeah, don't judge. What do you do on a Monday night between supper and dessert?
I'm going to skip the whole debate over the correctness of adding the soda or the ice cream first.
