Bake perfect artisan loaves and pizzas every time with the Mason Cash Innovative Kitchen Terracotta Baking and Proving Stone. Measuring 365 x 330 x 15mm, this versatile stone serves as both a baking surface and a proving lid for dough. Crafted from traditional terracotta, it features a grey glazed exterior and an unglazed interior. The unglazed surface absorbs moisture from dough, creating crispier crusts on bread and pizza. For proving, simply place the unglazed side down on any mixing bowl up to 290mm in diameter. This forms a natural seal, allowing dough to rise without the need for single-use plastic covers like cling film.
