Runny crepe batter is usually caused by too much liquid. To fix it, gradually add more flour, one tablespoon at a time, until the batter reaches a thin, pourable consistency.
A perfect crepe batter should be thin enough to spread easily on a hot pan but not so thin that it tears or becomes translucent. When your batter is too runny, it means the ratio of liquid to dry ingredients is off, specifically, there's too much liquid. Here's how to correct it:
Assess the Batter: Before adding anything, stir the batter well to ensure the ingredients are fully incorporated. Sometimes, the batter just needs a good mix.
Add Flour Gradually: The best way to fix runny batter is to add flour. Start with one tablespoon of flour at a time. All-purpose flour works well.
Mix Thoroughly: After each addition of flour, mix the batter thoroughly until the flour is completely incorporated. This prevents lumps from forming.
Check the Consistency: After mixing, check the consistency of the batter. It should be thin enough to pour easily but thick enough to coat the back of a spoon lightly. If it's still too runny, repeat steps 2 and 3.
Let it Rest: Once you've achieved the desired consistency, let the batter rest for at least 15-30 minutes. This allows the flour to fully hydrate, resulting in a smoother crepe.
Avoid adding too much flour at once, as this can lead to a thick, lumpy batter that's difficult to work with. It's always easier to add more flour than to remove it.
