There is some debate on where and when smoothies first appeared but most think they began showing up in the late 1940s in (where else) Souther California. If that is true then a “morning after smoothie” was probably among the first recipes developed.
I found this “morning after smoothie” recipe in a St. John’s Newfoundland newspaper. The author, Cynthia Stone, bills this smoothie as a non-alcoholic morning after remedy. I can’t vouch for that, but I can say it’s a healthy and tasty smoothie.
In your favorite blender mix:
1 cup skim milk
1/2 cup fat-free (or regular) plain yogurt
1/2 cup frozen blueberries
1 tbsp. rolled oats
1 tbsp. honey or maple syrup (sugar substitute works, too)
