Is it important to activate the sourdough starter before using it in the dough? Let's see...

My dears, You know very well that I am attentive to every comment, question, suggestion, and challenge you bring to me! Thanks to your input, I have accumulated a lot of experiment ideas. Today, I continue with video experiments on baking with sourdough starter. I am here to address two suggestions: Can we bake sourdough bread with an inactive starter? While anyone can bake small bread, can you bake a 2 kg loaf? I have answered both questions in this video. I hope my explanations are clear. If not, please write to me in the comments. Also, feel free to leave your suggestions and questions. Happy baking!
