Sourdough
A tangy, naturally leavened bread rich in flavor and tradition
What is a Sourdough?
Sourdough bread is made through a natural fermentation process involving wild yeast and lactobacilli. Its origins date back thousands of years, with its roots tied to ancient Egypt. Unlike commercial breads, sourdough uses a 'starter' culture rather than packaged yeast. Varieties include whole wheat, white, and rye sourdough.
Sourdough has a slightly tangy flavor due to organic acids formed during fermentation. Its texture is chewy with a crisp crust. Culinary uses range from sandwiches and toast to artisan dishes like sourdough pizza crust.
Nutritionally, sourdough is a source of carbohydrates, fiber, several B vitamins, and minerals like iron and selenium. It also contains beneficial compounds resulting from fermentation, which may aid gut health and lower its glycemic index compared to other bread types.
