5 products, 5 steps, 5 days – 1 perfect sourdough bread. Sourdough Kit 5 aids the home baker in cultivating one’s own yeast starter and in baking the perfect sourdough bread. The shape and the material of the five products – water bowl, flour bowl, starter bowl, baking dome and bench knife – are defined by their specific functions. With time the reduction-fired clay’s black hue lightens, revealing the product’s core colour. This change visualizes Wabi-sabi’s minimalistic philosophy in which the impermanence, the beauty of change and the act of doing are represented.
