For plain pancakes, do not add the lemon or blueberries. For buttermilk pancakes, use the juice of only one lemon or 2 tbsps. lemon juice. For another delicious option, try using 1 mashed banana or 1 grate apple instead of the lemon juice and blueberries. For a vegan-alternative, replace the egg with 1/2 c. unsweetened applesauce, use 1 c. soy or almond milk, and use 2 tbsp. vegetable oil instead of butter. To save time, mix the dry ingredients at home and portion into zip-top bags.
