Sour milk for baking question

[Pinky Tuscadero]

I have some soured milk that I made for baking. It's been out on the counter for almost two weeks. It's awesome-it even has fizz!
My question is how long will it be ok to use? Will it start to taste bad in banana bread and other baked goods?
Do you have a recipe that you love to use sour milk in?

I think it is a matter of how strongly you want to be able to taste the sour milk flavor. It should be just fine. Personally, I would use it sooner rather than later, just because we don't care for a very strong sour taste.

I just use it in any recipe that calls for buttermilk. Not too creative, I know. But, it does make yummy biscuits!
