So, is sourdough bread low carb? Yes, sourdough bread contains fewer carbohydrates because the sugars and starches are consumed during the fermentation process. Depending on how the dough is prepared, a small piece can contain as little as 5 grams of carbohydrates.
The traditional sourdough recipe involves three stages – making and feeding the starter, kneading, and shaping the loaf. Your ingredients should include sourdough starter, 250ml of water, 300g of unbleached flour, 10g of salt, 10g of sugar, and flavorless oil.
Without a sourdough starter, you need two things: something to make the bread sour, and something to make the bread rise. For rise, this recipe uses egg whites, baking powder, and baking soda, which provide plenty of lift. For sourness, you hydrate the dough with a combination of buttermilk and either sauerkraut juice or apple cider vinegar.
It uses psyllium husk to create chewiness and retain moisture, and three different leavening agents — egg whites, baking powder, and baking soda — to make sure the sourdough rises properly and doesn’t collapse under the weight of the flour. The result is a deliciously tangy keto sourdough that actually looks, feels, and tastes like real bread.
