โญ Sour Soy Yogurt (Unsweetened, Plain) (Best Vegan Option)
1:1 (replace Greek yogurt volume directly)Sour soy yogurt mimics the acidity and moisture of Greek yogurt but lacks the same protein density, which can reduce batter viscosity and the ability to trap air during cooking.
Use unsweetened versions to avoid flavor interference. Consider adding a tablespoon of oil or an extra egg white to improve tenderness.
Waffles will be less rich and may have a slightly drier crumb with a subtle soy flavor, but remain suitable for dairy-free diets.
