This is definitely more of an idea than a recipe, but it's such a smashing idea that I had to share! My brother's soon to be wife is the one who told me about rainbow floats when we were down visiting my family a couple of weeks ago. We may or may not have stopped at the grocery store that night to get the ingredients, and after we got home to Alaska, I may or may not have taken myself right over to the store again! That really says something coming from a person who is not especially fond of sherbet (until a couple of weeks ago, I hadn't had sherbet for maybe 10 years) or root beer floats, and who has a dessert/sweet treat once a week. There's just something about the sherbet-soda combination that is just perfect, though. Three flavors of ice cream if you go with rainbow sherbet, the bubbly tartness of the 7 Up, the creaminess and foam of the two together. Yum!
I even took a picture of my rainbow float to share, but it looked so bad that I figured we'd be better off without. A decent photographer would make it look beautiful, though, and it certainly tastes beautiful!
rainbow sherbet (or whichever flavor you want)
cold 7 Up
Scoop sherbet into tall glasses, then top with 7 Up. It will foam up a lot, so don't add too much soda at once! Serve with a straw and a long spoon.
