There are many recipes that call for buttermilk as one of their ingredients. Now the average person doesn’t (I’m assuming ) have a carton of buttermilk hanging out in their fridge, and if the urge to bake strikes and you are using a recipe that needs buttermilk I’m sure that a trip to the store just for one ingredient may cause some of us to put our baking off for another day.
I’ve been in the situation many times and with some research I found that there is a cheat that you can use AND it’s so simple.
For every cup of buttermilk you need : 1 cup of milk + 1 Tbsp of vinegar Let the vinegar sit in the milk for a few minutes so that it can work it’s magic and you’re good to go.
You may ask why you cant just add the milk. Well my guess is that your recipe also asks for baking soda/ bicarbonate of soda and like I explained in my post about baking powder vs baking soda , you need an acid for the baking soda to react with. The milk alone is neutral, so that alone will not work and your cake won’t rise as it should, hence you need the vinegar as well.
I’ve used this countless times and it’s worked great for me.I hope this hint helps and if you try it, please leave me a comment about how it worked for you.
