You can skip the dry. It's far more likely to fail than a starter, as the starter is more ideal conditions for yeast growth. If a starter fails, it probably means the yeast is too old or the water was too hot. I use a digital kitchen thermometer to check temperature.Trying to cover all the bases. My first batch I just added dry on top of fruit and hoped for the best. Then I read just about EVERY post in this forum and many here swear that a guarantee to fermentation was to make a starter. I didn’t want to take a chance i prepared starter wrong or something. The dry goes on first and then I prepare the starter With the other half. By the time the starter batch goes on, the dry should be beginning to bloom as well.
