The oven-safe ceramic and the holes in the lid as well as at the base ensure moisture retention during baking. The crust becomes crispy while the crumb remains soft. The shape allows for a variety of breads using different types of flour, such as chestnut, flaxseed, rice, and gluten-free flour. Doughs that are more liquid than those for white bread require more maintenance during baking and are more challenging to achieve with the bread set. The bread becomes crispy without needing to remove it from the mold during baking or adding water to the oven. It takes up minimal space and is easy to clean. 10-year warranty.
