Finnish Pulla
The other day, I was talking to a friend of mine about my tiny little cottage baking business. He asked what kind of bread I baked -- I'm not sure he'd ever heard of challah. But we started talking about a kind of bread that his Finnish grandmother used to bake all the time: pulla. Fast forward to about a week later and I sent him a picture of that week's batch of challah and he immediately responded that it looked EXACTLY like his grandmother's pulla. Needless to say, my curiosity was piqued.
