What is a blue pancake?

There's no one definitive "blue pancake" recipe, but here are a few possibilities:

* Pancake batter with blue food coloring: This is the most straightforward option. You can use a store-bought pancake mix or make your own, then add a few drops of blue food coloring to the batter.

* Pancake batter made with blueberries: Blueberry pancakes are a classic, and they can be quite blue depending on the amount of blueberries used.

* Pancake batter made with Spirulina: Spirulina is a blue-green algae that can be added to food for its nutritional benefits. It will give your pancakes a distinct blue-green hue.

* Pancake batter flavored with blue curaçao: Blue curaçao is a blue-colored liqueur often used in cocktails. You could add a splash to your pancake batter for a sweet and fruity flavor.

Ultimately, a "blue pancake" is any pancake that is blue in color. The exact recipe and flavor will depend on your preferences.
