This looks excellent, I might substitute hatch for poblano as I have hatch chilies at the moment.
So, masa harina. An ingredient I haven't used. I have bread flour, whole wheat flour, and white and yellow cornmeal. Substitution possible?
Or heck, there is a Mexican grocery on my way to work I've been wanting to explore. I bet they'd have it.
A corn based flour? I've just started experimenting with corn meal. I'm kind of excited as my first attempts at corn bread have really sucked. Which means this is an area of cooking and baking I have a lot to learn about.
I really like the idea of this recipe. I will try to do it exact once I find some masa harina. Then of course, I'm gonna mess with it shamelessly.
sourdough isn't a recipe, it is a process.
