The Milltop salt and pepper mill set from Joseph Joseph is innovative and practical. While other salt and pepper mills often leave behind residue, any excess ground salt or pepper falls back into the Milltop mills after use. The trick: the grinding mechanism is located at the top of the mill. This inverted design prevents crumbs on the countertop and dining table. The mills are made of plastic, with a ceramic grinding mechanism, and they are easy to refill thanks to a large opening at the bottom. To grind, simply turn the mill upside down and twist at the base. The grind size can be adjusted by turning the stainless steel lid. Visually, the two mills differ in color: the salt mill is in a light gray, while the pepper mill is in a dark gray.
