To make one cup of buttermilk, put 1 TBS lemon juice or white vinegar in a measuring bowl. Add enough milk to equal one cup. Let sit for 5 minutes. Use as you would buttermilk.
This is one of my favorite kitchen tips, and to be honest, I haven't purchased buttermilk in years! It's saved me a lot of money...not having to spend $3 on a quart of buttermilk that you probably won't even finish up before it spoils, really adds up!
How long does this keep...if you don't need all of it?
ReplyDeleteHi!
DeleteI don't actually know the answer to that...so I try to scale down the recipe to only what I need. For example, if I only need 1/2 C of buttermilk, I will only use 1/2 TBS (or 1.5 tsp) of lemon juice.
