01 - Combine blueberries, sugar, water, and lemon juice in a small saucepan. Bring to a gentle simmer over medium heat. Cook for 8–10 minutes, stirring occasionally, until berries burst and syrup thickens slightly. Remove from heat and keep warm while preparing pancakes.
02 - In a large mixing bowl, whisk together ricotta cheese, egg yolks, milk, granulated sugar, lemon zest, lemon juice, and vanilla extract until completely smooth and well combined.
03 - In a separate medium bowl, sift together flour, baking powder, baking soda, and salt to ensure even distribution of leavening agents.
04 - Add the dry ingredient mixture to the wet ingredients. Stir gently with a spatula or wooden spoon until just combined—small lumps are acceptable. Do not overmix as this will result in dense pancakes.
05 - In a clean, grease-free bowl, beat egg whites with a hand mixer or whisk until soft peaks form when the beaters are lifted. Gently fold the whipped egg whites into the batter using a spatula, being careful not to deflate the mixture.
06 - Place a non-stick skillet or griddle over medium heat. Add 1 teaspoon of butter and allow it to melt and coat the surface evenly.
07 - Pour approximately 1/4 cup of batter per pancake onto the preheated skillet. Cook for 2–3 minutes until bubbles form across the surface and edges appear set. Flip carefully and cook for an additional 1–2 minutes until golden brown and cooked through. Repeat with remaining batter, adding more butter as needed.
08 - Stack warm pancakes on serving plates. Generously drizzle with the warm blueberry syrup. Optionally garnish with additional fresh blueberries, a dusting of powdered sugar, or a dollop of whipped cream.
