Dry Mix for Light and Fluffy Buttermilk Pancakes

Yield: 4 to 6 servings

Time: 35 minutes including prep
Difficulty: Easy

Basic Dry Pancake Mix:

• 10 ounces (about 2 cups) all-purpose flour
• 1 teaspoon baking powder
• 1/2 teaspoon baking soda
• 1 teaspoon kosher salt
• 1 tablespoon sugar

For Each Batch of Pancakes

• 2 large eggs, separated
• 1 1/2 cups (about 12 ounces) buttermilk
• 1 cup (about 8 ounces) sour cream (see notes)
• 4 tablespoons unsalted butter, melted, plus more for serving
• Warm maple syrup

Instructions

1. For the Dry Pancake Mix: Combine flour, baking powder, baking soda, salt, and sugar in a medium bowl and whisk until homogenous. Transfer to an airtight container. The mix will stay good for 3 months. 
2.  For each Batch of Pancakes: Place one batch of dry mix in a large bowl. In a medium clean bowl, whisk the egg whites until stiff peaks form. In a large bowl, whisk the egg yolks, buttermilk, and sour cream until homogenous. Slowly drizzle in the melted butter while whisking. Carefully fold in the egg whites with a rubber spatula until just combined. Pour the mixture over the dry mix and fold until just combined (there should still be plenty of lumps).
3. Heat a large heavy-bottomed nonstick skillet over medium heat for 5 minutes (or use an electric griddle). Add a small amount of butter or oil to the griddle and spread with a paper towel until no visible butter or oil remains. Use a 1⁄4-cup dry measure to place 4 pancakes in the skillet and cook until bubbles start to appear on top and the bottoms are golden brown, about 2 minutes. Carefully flip the pancakes and cook on the second side until golden brown and completely set, about 2 minutes longer. Serve the pancakes immediately, or keep warm on a wire rack set on a rimmed baking sheet in a warm oven while you cook the remaining 3 batches. Serve with warm maple syrup and butter.

Notes:

•  Pancake dry mix can be scaled up as many times as you'd like. Each batch of pancakes takes 11 ounces of dry mix to make (about 2 cups plus 2 tablespoons). The sour cream can be replaced with more buttermilk.
• Very gentle spreading within the first couple of seconds after putting the batter in the pan makes for thinner, wider pancakes.
