Place the flour in a bowl and make a well in the middle.
In another bowl, whisk the milk and eggs together. Pour mixture into the flour well and stir with a whisk until smooth.
Cover with plastic wrap and let sit at room temperature for 30 minutes.
Heat a non-stick skillet and melt a small amount of butter in it. Add 80 mL (1/3 cup) of the mixture and spread evenly to cover the bottom and create a thin crepe.
Cook 1 minute and turn to finish cooking.
Spread the hot crepe with butter, sprinkle with sugar and add a squeeze of lime juice.
