? about buttermilk
How do you know when buttermilk goes bad? Is there a sign? how long could you leave it in the fridge before it goes bad? I've always had this question and everytime i get my buttermilk out i wonder 'is it spoiled? or it is ok?" I KNOW it's supposed to taste sour and the smell isn't great either, that's what throws me off because i don't know when it goes bad, KWIM?
I don't want to throw it out if it's not spoilt, but i certainly don't want to cook w/ it if it's gone bad! help!
