To make Alton Brown crepes, you will need all-purpose flour, sugar, kosher salt, milk, eggs, and unsalted butter. In a blender, combine the flour, sugar, kosher salt, milk, eggs, and melted butter and blend until the mixture is smooth. Let the batter rest in the fridge for at least an hour. Heat a non-stick pan over medium-high heat and grease with butter. Pour approximately 1/4 cup of batter into the pan and swirl it around until the pan is coated evenly. Cook for 1-2 minutes until the bottom of the crepe is golden brown and then flip it over using a spatula and cook on the other side for an additional 30 seconds. Repeat this process until the batter is finished, and then serve with your preferred filling.
