If you're going to use a beer reduction (see notes), pour it into a sauce pan. High heat until it starts to bubble and then back down to a simmer. Let it reduce until you have about 8 oz.
Beat the egg in a bowl
Combine all the dry ingredients into a bowl and stir until well blended. I used two bowls here with the ingredients split as I wanted to create a spicy batch for myself and a non-spicy batch for my family. See my notes about that awesome pepper powder you see in the pic!
Add the beer and egg to the bowls.
Stir until you have a smooth, thick paste. Your batter is ready to go!
