⭐ Greek Yogurt (Best Nut-Free Option)
1:1 by volumeGreek yogurt is strained, resulting in a thick, creamy texture similar to sour cream, and it contains lactic acid which imparts a comparable tanginess. This acidity helps tenderize the gluten in the crepe batter, maintaining softness.
When substituting, use plain Greek yogurt to avoid added flavors or sweetness. If the batter becomes too thick, thin slightly with a small amount of milk or water to maintain proper consistency.
Compared to sour cream, Greek yogurt produces crepes with a similar moist crumb and subtle tang, preserving the intended flavor profile and texture.
