Start by whisking eggs, milk, water, and melted butter together until smooth. Add flour, lemon zest, sugar, poppy seeds, and salt. Mix until just combined.
Cover and let the batter rest in the fridge for about 30 minutes. This helps relax the gluten and improves texture.
Place a non-stick skillet over medium heat and lightly coat it with butter. Make sure the pan is evenly heated before adding batter.
A properly heated pan ensures thin crepes that don’t stick or tear easily during cooking.
Pour about 1/4 cup of batter into the center of the pan and swirl to spread evenly. Cook for 1–2 minutes until edges lift slightly.
Flip gently and cook the other side for about 30 seconds until lightly golden.
Transfer cooked crepes to a plate or baking tray and keep warm in a low oven. Stack them gently to avoid tearing.
Repeat the process with the remaining batter, adding butter as needed between batches.
Dust with powdered sugar and top with fresh blueberries if desired. Serve immediately for the best flavor and texture.
You can also fold or roll them depending on your presentation style.
