Hi Kate.
I'm interested in helping you test recipes. I've been baking sourdough for 10 years. It's the only kind of bread I eat now. For a long time I shaped round boules and baked in a cast iron pot. Lately I've been baking more of a sandwich style mostly white bread (using Sunrise Flour Mill's Heritage Bread Blend along with some rye and WW) because my 2 year old grandson likes a softer bread. I also have a good supply on hand of Azure Standard ultra unifine Spelt and WW bread flour. I have a flour mill and a supply of rye, einkorn, and wheat (hard white and soft) berries that I haven't used in about a year. I hope they're still good! I bake in a gas oven. Let me know if I can help you. I will take pictures. I love trying new recipes!
