My technique video below demonstrates Pre-Shape and Shape for 3 loaves of sourdough. I'll teach you how to build tension for that fantastic oven-spring. We'll work with 3 loaves of dough: 2 are my Beginner Tartine Sourdough Bread recipe, and the 3rd is an intermediate loaf using whole wheat and spelt.
I also show you how to check for "PROOFING", and preparing your bannetons for your overnight cold retard.
If you're new to sourdough - please check my Sourdough School pages, my beginner recipe video, and my other technique videos - all in the Sourdough Video Tutorials Tab. There I have how I worked the stretch and folds, and coil folds for the loaves we shape below.
And, finally! - if you'd like to see how I score and bake this - follow this link --> Technique: Learn To Score and Bake Sourdough. Demonstrating Three Loaves.
