Prep the ricotta: If your ricotta is very wet, place it in a fine-mesh strainer or press gently with paper towels to remove excess moisture. This keeps the batter from getting runny.
Mix the dry ingredients: In a medium bowl, whisk together flour, sugar, baking powder, and salt.
Set aside.
Whisk the wet base: In a large bowl, whisk the ricotta, milk, egg yolks, vanilla, and lemon zest until smooth and creamy.
Combine gently: Add the dry ingredients to the ricotta mixture. Stir with a spatula until just combined. The batter should be thick with a few small lumps.
Do not overmix.
Whip the egg whites: In a clean bowl, beat the egg whites to soft peaks using a hand mixer or whisk. They should look glossy and hold a gentle peak.
Fold in for fluff: Fold the egg whites into the batter in two additions. Use a light hand to keep the air in the batter.
Stop as soon as no big white streaks remain.
Rest the batter: Let the batter sit for 5–10 minutes. This short rest helps the flour hydrate and the pancakes rise more evenly.
Heat the pan: Warm a nonstick skillet or griddle over medium heat. Add a small pat of butter or a thin swipe of oil.
The surface is ready when a drop of water skitters across.
Cook the pancakes: Scoop about 1/4 cup batter per pancake. Spread gently into a circle if needed. Cook until bubbles form on top and the edges look set, 2–3 minutes.
Flip and finish: Flip carefully and cook another 1–2 minutes, until golden and cooked through.
Lower the heat if they brown too fast.
Serve warm: Stack on plates and top with butter, syrup, fresh berries, or a dusting of powdered sugar. For a savory spin, try a dollop of ricotta, a drizzle of olive oil, and cracked pepper.
