National Sourdough Bread Day is celebrated on April 1st each year. This day is dedicated to honouring the long tradition and unique flavour of sourdough bread. Take this opportunity to showcase your sourdough bread-making skills, experiment with different sourdough starters, and offer special sourdough bread-based dishes to your customers. It’s a great time to educate people about the art of sourdough bread-making and its cultural significance.
