Curdled Soy Milk + Apple Cider Vinegar for Dairy Buttermilk
The complete culinary guide to replacing Dairy Buttermilk with plant-based Curdled Soy Milk + Apple Cider Vinegar. Exact conversion ratios, texture chemistry, and chef techniques.
How do you substitute Dairy Buttermilk with Curdled Soy Milk + Apple Cider Vinegar?
To substitute Dairy Buttermilk, use Curdled Soy Milk + Apple Cider Vinegar at a conversion ratio of 1 cup unsweetened soy milk + 1 tbsp apple cider vinegar or lemon juice per 1 cup dairy buttermilk (240ml) (Stir together and let rest 5-10 minutes until curdled and thick). It is ideal for leavening, moisture, flavour and provides a similar texture and binding profile.
The acid in the vinegar reacts with baking soda in your batter to create carbon dioxide gas bubbles, resulting in a significantly lighter and fluffier rise than plain plant milk alone.
