Hey! Here's a photo from my archives. 20% rye sourdough (with 25% high gluten flour and the rest AP). Overnight bulk ferment at 15C. For a while during COVID I was baking once weekly for some supplemental income. This was early on in my learning process for how to manage larger batches. It was helpful to have a commercial fridge available to slow things down, as I am in the tropics.
I made my first 20% rye sourdough last weekend. It was excellent. Too bad I hadn’t tried it sooner.
