Hot Dr. Pepper is the Holiday Drink from the 1950s I Just Had to Try.. Here’s What I Thought..

2How to Make Hot Dr Pepper
It’s not a difficult recipe! Heat up some Dr Pepper to 180°F. Then, pour it over a thin lemon slice. (You can add rum to make a Schuss-Boomer, but I tried the mocktail version.) Some vintage Dr Pepper ads for this drink recommend making it with Diet Dr Pepper. So I bought all types of Dr Pepper at my store, and ended up trying regular Dr Pepper, Diet Dr Pepper and Dr Pepper Cherry.
