Carrot Pancake Batter
Mix 1 g of salt with 125 g shredded/chopped carrots until moisture begins to draw out. Let sit for at least one hour. Squeeze liquid out of carrots through a kitchen towel until dry.
In a bowl mix flour, sugar, baking powder, spices, salt, and 2 T brown sugar. Add the salted carrots to the dry and coat evenly.
Mix the egg, carrot buttermilk, vanilla extract, and oil together and add to the dry carrot mix. Mix as little as possible to combine.
Heat a skillet or non-stick pan over medium-high heat. Add one tablespoon of butter. Spoon pancake batter into the pan. Cook on one side until tiny bubbles start appearing on top of the batter. Flip. Cook on the other side until cooked through.
