01 - Combine blueberries, sugar, water, and lemon juice in a small saucepan. Bring to a simmer over medium heat. Cook for 8–10 minutes, stirring occasionally, until berries burst and syrup thickens slightly. Remove from heat and keep warm.
02 - In a large bowl, whisk ricotta, egg yolks, milk, sugar, lemon zest, lemon juice, and vanilla extract until smooth and fully combined.
03 - In a separate medium bowl, sift together flour, baking powder, baking soda, and salt to ensure even distribution.
04 - Add dry ingredients to wet mixture and stir gently with a spatula until just combined. Do not overmix—small lumps are acceptable.
05 - Using a hand mixer or whisk, beat egg whites in a clean bowl until soft peaks form. Gently fold into batter until incorporated, maintaining as much air as possible.
06 - Heat a non-stick skillet or griddle over medium heat. Add a small amount of butter. Pour 1/4 cup batter per pancake. Cook for 2–3 minutes until bubbles form on surface and edges appear set. Flip and cook 1–2 minutes until golden and cooked through.
07 - Stack warm pancakes on plates and drizzle generously with warm blueberry syrup. Serve immediately while hot.
