I've been baking sourdough bread with a Rational combi for the last 3 months, & have had 'good' results. But I'm not satisfied with the oven spring I'm getting. I'd love for any of you to look over my recipe & baking instructions & see if you can figure out what's keeping the bread from generating those beautiful, large air bubbles & the wide splits where I've scored? I'd love to hear what any of you have to say to this.
Here is a link for my recipe, I wrote it out for friends who have no experience with SD bread, but wished to learn- so it's rather detailed, & easy to follow.
I bake it in a preheated oven at 400° (on a hot, iron deck) with full steam for 25 minutes, & then at 400°for 20 minutes with no steam.
(I've also tried 500° for the first bake settings, still playing around with the temp, trying to find the best.) the picture I've attached here is of the biggest holes I've yet seen.
