Uuni Stack makes dough proving organised and easy. The multi-use product is also great for cooking prep, chopping and stylish storage. Great dough is the bedrock of a great pizza and proving (or proofing, if you prefer) plays an important part in getting it right. We used to cover plates with cling film or find random containers to fill with dough balls but always found this to be… not such a great process. And so, Uuni Stack was born.
