⭐ Non-Dairy Yogurt (Soy or Coconut) Thinned with Water (Best Dairy-Free Option)
3 tablespoons non-dairy yogurt + 1 tablespoon water Quick tip: Provides acidity but may affect flavor and texture noticeably.
Non-dairy yogurts contain acids that can mimic buttermilk's tang and help with emulsification, but their base ingredients and textures differ significantly from dairy, which can impact the sauce.
Choose plain, unsweetened varieties and thin with water to approximate buttermilk's consistency. Be cautious of added stabilizers or flavors.
This substitute may introduce a slight coconut or soy flavor and a different mouthfeel, which can alter the traditional Hollandaise experience, but it is suitable for dairy-free diets.
