White Vinegar (Best Option)
1 teaspoon per 1 tablespoon lemon juiceWhite vinegar works well because it has a similar acidity level to lemon juice, which is important for activating any baking soda and balancing the batter's pH. This acidity helps tenderize the gluten and contributes to the lightness of the crepes.
When using white vinegar, measure carefully to avoid overpowering the batter with vinegar flavor. Itβs best to use distilled white vinegar for a neutral taste. Mix it thoroughly into the batter to ensure even acidity.
The final crepes will have a slightly different flavor profile, lacking the citrus aroma of lemon juice, but the texture and rise will remain similar, making it an excellent functional substitute.
