Crepes: Combine the eggs, milk, water and flour in a blender and pulse for 10 seconds. Place the crepe batter in the refrigerator for at least 1 hour. (This allows the bubbles to subside so the crepes will be less likely to tear during cooking.) The batter will keep for up to 48 hours.
Heat a small non-stick frypan. Add butter to coat. Pour 2-3 tablespoons of batter into the center of the frypan and swirl to spread evenly. Cook for 30 seconds then flip. Cook for another 10 seconds and remove to the cutting board. Lay them out flat so they can cool, you can stack the crepes, they will not stick to each other. Continue until all batter is gone.
Filling: Whip the cream until stiff peaks form (be careful not to over whip, or you’ll make butter!)
Gently fold the lemon curd into the whipped cream. Refrigerate for 1 hour. Stir before using.
To Assemble: Place 1 crepe on a flat serving dish. Spread about 1 heaped tablespoon of the whipped lemon cream on top of the crepe. Continue layering the crepes and whipped lemon cream, ending with a plain crepe on top. Refrigerate for about 1 hour or until firm.
To Serve: Dust icing sugar of the top of the assembled crepe cake then top with fresh berries.
