White Vinegar (Best Option)
1 teaspoon per 1 tablespoon of lemon juiceWhite vinegar works well as a substitute because it provides the acidic component necessary to balance the richness of the eggs and milk in French Toast. The acid helps break down the proteins in the egg mixture, tenderizing the bread and contributing to a light texture.
When using white vinegar, measure carefully as it is more potent than lemon juice. Start with the recommended ratio and adjust slightly if needed. Mix thoroughly to ensure even distribution.
Compared to lemon juice, white vinegar imparts a more neutral acidity without citrus notes, preserving the traditional flavor profile of French Toast while maintaining the desired texture.
