Separate egg whites from the yolks.
To the egg yolks, add milk and vanilla extract and mix.
Sift in flour and baking powder then mix until combined.
Begin to preheat your pan over low heat (about 315F). You want to do this in advance because the merengue will star to become runny so you want to get it on the pan ASAP.
In your bowl with egg whites, add lemon juice then begin to whisk, adding in the sugar in stages, 1 tbsp at a time. This will allow the merengue to form stiff peaks easier.
Once stiff peaks have been formed, mix ¼ of the merengue into the egg yolk mixture to lighten the batter. This will help the folding process be easier.
Add the remaining amount of your merengue into the batter then gently fold until one smooth color making sure not to over mix.
Place into a piping bag and immediately pipe into your preheated pan. You want to make your pancakes tall and even because when you flip, they will shrink.
Splash ½ tbsp of water into the pan and cover for 5 minutes.
Flip pancakes using a spatula then add more water and cover again for 5 minutes.
