Light & Fluffy Pancakes

I adapted this recipe from 'The Best Recipe Cookbook'. I usually don't have buttermilk in the house so I substitue 1 cup clabbered milk (1 Tbsp. white vinegar plus enough milk to make one cup, let stand 5 minutes before using) or 1 small container yogurt plus enough milk to make 1 cup wet ingredients. If using yogurt you'll probably need to add 1-2 Tbsp. extra milk because the batter will be thicker.

• Ready In: 25 mins
• Serves: 2-3

Ingredients

• 1  cup all-purpose flour
• 2  teaspoons sugar
• 1⁄2 teaspoon salt
• 1⁄2 teaspoon baking powder
• 1⁄4 teaspoon baking soda
• 3⁄4 cup buttermilk
• 1⁄4 cup milk (plus a Tbs. or so extra if batter is too thick)
• 1  large egg, separated
• 1  tablespoon unsalted butter, melted
•  cooking spray

Directions

1. Whisk dry ingredients in medium bowl. Pour buttermilk and milk into a 2 cup Pyrex measuring cup. Whisk egg white into milk mixture. Mix egg yolk with melted butter, and then stir into milk mixture. Dump wet ingredients into dry ingredients all at once; whisk until just mixed.
2. Meanwhile, heat griddle or a large skillet over medium-high heat coated with cooking spray. Pour batter, about ¼ cup at a time, onto griddle, making sure not to overcrowd. When pancake bottoms are brown and top surface starts to bubble, 2 to 3 minutes, flip cakes and cook until remaining side has browned, 1 to 2 minutes longer.
3. VARIATION: BLUEBERRY PANCAKES - Follow recipe for Light and Fluffy Pancakes, pouring a little less than ¼ cup batter at a time onto the griddle. Starting with ½ cup blueberries, drop about seven blueberries on top of each pancake. Proceed as directed in master recipe.
4. VARIATION: WHOLE WHEAT PANCAKES - Follow recipe for Light and Fluffy Pancakes, substituting ½ cup whole wheat flour for ½ cup of the all-purpose flour.
