Sift the flour and baking powder. Stir in sugar & 1/2 lemon zest (grate 1/2 the lemon!). Add eggs (original recipe called for 1 egg) & lemon juice. Mix until batter is smooth and thick. Add blueberries. Cook over hot griddle making mini pancakes (3 inches in diameter) or big ones (5 inches). By the way, make sure you cook on medium or you'll burn your pancakes! I like mine with Palomar 100% strawberry fruit jam. Enjoy!
