The tiny surface bubbles that give lahoh its name (canjeero roughly means 'full of holes') form entirely from natural fermentation, with no baking soda or other rising agent needed.
Canjeero, also known as lahoh, is a fermented flatbread cooked on a griddle until covered in small bubbled holes, similar in method to injera but smaller, thinner and slightly sweeter. It's eaten with honey and sesame oil or torn and dipped into stews.
