White Vinegar (Best Option)
1 tablespoon per 1 tablespoon of lemon juiceWhite vinegar is a clear, mildly acidic liquid that effectively mimics the acidity of lemon juice, which is critical for activating baking soda in cinnamon rolls. This activation produces carbon dioxide, helping the dough rise and creating a tender crumb.
When substituting, use an equal volume to lemon juice. Because vinegar has a sharper acidity, ensure it is well incorporated to avoid any residual vinegar taste. The aroma typically bakes off, leaving the rolls tasting as intended.
Compared to lemon juice, white vinegar does not contribute citrus notes but preserves the chemical leavening process, resulting in cinnamon rolls with similar texture and rise.
