Sourdough Slice
A tangy artisan bread with a rich flavor profile and notable digestive benefits
What is a Sourdough Slice?
Sourdough is a type of bread made with a natural fermentation process using wild yeast and lactic acid bacteria. Its origins date back thousands of years, with ancient civilizations leveraging fermentation to produce leavened breads. Today, sourdough comes in a variety of forms, including white, whole grain, and rye-based loaves.
The bread is known for its mildly tangy taste, a result of lactic acid bacteria fermentation, and its chewy, flavorful crust. Its interior is soft and airy, making it a versatile choice for sandwiches, toasts, or simply enjoying with butter. The fermentation also provides it with a prolonged shelf life compared to regular bread.
Nutritionally, sourdough boasts a moderate amount of carbohydrates for energy, a lower glycemic index than conventionally leavened breads, and trace minerals like iron and magnesium. The fermentation also enhances digestibility and can make nutrients more bioavailable.
