Liquid nondairy alternatives
You can also use liquid milk substitutes, such as almond, oat, or soy milk, to create a dish dairy-free or vegan. Liquid milk substitutes should only be used in recipes that call for both milk powder and extra water, just like when using actual milk. The substitute is also the same: for every 1/4 cup (32 grams) of dry milk and 1 cup (240 mL) of liquid in the original recipe, use 1 cup (240 mL) of milk alternative.
Use 1 cup (240 mL) of a milk substitute and 1 tablespoon (15 mL) of vinegar or lemon juice in place of buttermilk powder. Before adding the mixture to your recipe, let it sit for 5 to 10 minutes. If you use plant-based milk in place of animal milk, your sweet or savory dish's nutritional value and flavor will change since plant-based milk has various types and levels of nutrients as well as tastes.
