In a medium bowl, whisk together flour, granulated sugar, baking powder, baking soda, salt, and lemon zest. Set aside.
1 ¾ cups (210g) all-purpose flour, 2 tablespoons (25g) granulated sugar, 1 tablespoon baking powder, ½ teaspoon baking soda, ½ teaspoon salt, zest of 2 medium or 3 small lemons
In a liquid measuring cup, stir together the milk and lemon juice. Set aside while you prepare the rest of the wet ingredients.
1 cup (240mL) milk, ¼ cup fresh lemon juice
In a large bowl, combine the ricotta cheese, eggs and vanilla extract. Whisk until well combined. Whisk in the milk-lemon juice mixture until smooth.
¾ cup (186g) ricotta cheese, 2 large eggs, 1 teaspoon vanilla extract
Pour the dry ingredients into the wet and use a rubber spatula to mix until barely combined. The batter will be thick. Be careful not to overmix.
Heat an electric griddle or non-stick skillet over medium heat. Grease the griddle or skillet with butter (you can skip the butter if using a non-stick griddle that doesn't require greasing, although I find that using butter helps the edges get nice and golden.)

Scoop the pancake batter onto the griddle, using about 3 tablespoons of batter per pancake. Let pancakes cook on the first side until bubbles form and the pancake bottoms are golden, about 3 minutes. Flip the pancakes and cook them on the second side until golden, about 2 minutes. Serve pancakes with fresh berries and maple syrup, or as desired.
