Hello. I have several questions about starters. Please bear with me being new at this. First, the starter I am using is 1 cup flour, 1 cup water, 1 tsp yeast. First question. Can I use wheat flour in my starter? Second question. I have read that after being refrigerated, it will last for two weeks. Can I just work from this one starter for two weeks and not add to it to make it grow. In other words, I would like to have a starter, use it and then make another starter. I don't want one that I have to feed. Is this possible? Also, can I add starter to any bread recipe? Can I use very small amounts of this starter, say 1/4 cup or so. Is a starter to make your bread sour or flavorful or is it also for its rising capabilities? Lots of questions here. Hope someone can answer each one for me, thank you.
