Man. It's so hard to find buttermilk here in Jakarta. I'm saying that with regret because there are a lot of great recipes out there that required buttermilk and i just had to skip them because I had no idea where to get one.
But then i found this :
Thank you so much Kay from Kayotic Kitchen! She stated in her blog how to make buttermilk. Geez, I never knew that we could make buttermilk. Kay also blogs about how to make your own butter! Butter!! I am amazed.
I do think her blogs are one of those great blog out there that are worth to see. She mostly cook than baked, but her recipes are easy, yummy and not to mention she is also an amazing food photographer! :)
