Notes
This dry buttermilk substitute is good in small quantities for making dry mixes like our dry ranch dressing mix, cake mixes, muffins, and pancakes.Can I use this as a replacement for fresh buttermilk?You could use it as a replacement for fresh buttermilk in baking if you are desperate by mixing ¼ cup of dry buttermilk substitute and 1 cup of water.However, you will find that it is watery in consistency and does not have the same thick consistency as real buttermilk, which you may need for some recipes.You can find better substitutes for fresh buttermilk on our “What Can You Use Instead Of Buttermilk” page.
