Hi Kate,
I would love to be a tester! I have edited courseware and written instructional design, so I think I can follow your recipes! Currently this summer, I am learning to perfect sourdough whole grain breads. I used to be good at making yeasted breads, but gave that up for gluten-free 15 years ago and recently (past few months) have been switching back to Weston Price and sourdoughs. I think it isn't the modern wheat necessarily that is causing major problems, just contributing. Pesticides and GMOs with poor soils are likely doing the bulk of it. Anyway, trying traditional methods with a host of other ways to get more nutrition and less bad stuff!
On my sourdough journey I have been using the "scrapings" method and I have a very active starter that I got from a friend. I am now going through the Bittman Bread book and I'm getting so good. Baking recipes twice really helps. I made a Rye bread yesterday, and today was a Brioche sandwich loaf. These are all whole wheat and I am finally getting the lift and crumb right! I've made sourdough focaccia, pretzels -- tomorrow is a scallion pancake, and I think I'm prepping a cinnamon roll for the day after.
I totally would love to help test recipes. Here's some of my recent pictures.
I use only whole grains and have access to einkorn, wheat, emmer, rye, buckwheat. I could get spelt and probably whatever else whole grain. I have a mill and hard red wheat berries. I'm not sure what to do with whole einkorn, but I have some of that. I thought someone said you have to de-hull it somehow before you grind it. So I'm not sure how that works. But it's always nice to learn something!
I don't have any of the other kinds of ovens, just a regular oven.
Good luck with the book. I'm excited for you and for more people learning this skill! So thank you for writing this.
