I've been working on a sourdough starter for about 3 weeks and counting! I'm getting bubbles and some growth but it never doubles in size. My container is clear plastic so I can see growth( I've marked it so see if it grows). The container is about 5" in diameter. I have 8 oz of starter and I add 8 oz of flour/water (each at 100% hydration - half flour/half water).The growth varies from one feeding to another. I'm trying to be consistent by always keeping it in the pantry but some days I have growth and others there is no growth. It smells fabulous! It floats! I'm feeding it every twelve hours. When will it be ready for me to use to make bread??? The lack of growth is keeping me from taking the plunge. I've got a dutch oven so I'm ready to go. Also, what recipe would you recommend for a first loaf? I've made plenty of bread and have used other people's starters but never my own. I appreciate any help you can give me.
