In a large bowl, stir all ingredients together until well blended. Store in a resealable plastic bag. Yield: about 7 1/2 cups pancake mix, enough for 3 batches of pancakes.
To make pancakes: In a medium bowl, combine 2 1/2 cups pancake mix, 1 1/4 cups water, 1 egg, and 2 tablespoons vegetable oil. Stir just until moistened. Heat a greased griddle over medium heat. For each pancake, pour about 1/4 cup batter onto griddle and cook until top of pancake is full of bubbles and underside is golden brown. Turn with a spatula and cook until remaining side is golden brown. Regrease griddle as necessary. Yield: about 1 dozen 5-inch pancakes.
