Sourdough bread is a wonderful traditionally prepared product in which time is one of the most im-portant ingredients. ‘Henry’, our home-made sourdough starter, serves as the common thread running through our production process and our product range. Our mother sponge is the 40-year-old foundation on which our expertise is built. Each day, we use a portion of this sourdough starter to create our home-made sourdough. We keep Henry alive by feeding him every day. The older a mother starter is, the more stable the cultures will be and the more aroma is released – all of which results in bread that is packed with flavour. This means that you will taste a unique product that is unparalleled and spe-cific to Bio Bakkerij De Trog.
