01 - In a small saucepan, combine blueberries, sugar, water, and lemon juice. Simmer over medium heat, stirring occasionally, until berries burst and syrup thickens slightly, about 8–10 minutes. Remove from heat and set aside.
02 - In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt until evenly combined.
03 - In a separate bowl, mix ricotta cheese, milk, egg yolks, lemon zest, lemon juice, vanilla extract, and melted butter until smooth.
04 - Add the wet ingredients to the dry ingredients and stir gently until just combined; avoid overmixing to maintain tenderness.
05 - Beat egg whites until soft peaks form and gently fold them into the batter until just incorporated, enhancing fluffiness.
06 - Heat a nonstick skillet or griddle over medium heat, brushing lightly with butter. Pour 1/4 cup batter per pancake. Cook until bubbles appear and edges set, 2–3 minutes. Flip and cook an additional 1–2 minutes until golden and cooked through. Repeat with remaining batter.
07 - Serve pancakes warm, topped generously with blueberry syrup.
