How to season with one hand busy stirring the pot? Every chef knows the dilemma. With the Bistro Gravity salt and pepper grinder it doesn"t get any easier: tilt the grinder over the pot and it does it all by itself. A ball inside the grinder sets the electric grinder in motion once it"s angled - all you have to do is pick whether you want pepper or salt. The grinder works for other spices as well. Both, the salt and the pepper grinder are adjustable in fineness and they"re easily refilled by lifting the grinder"s cap. Available in black, orange, red and green. Requires 6-AAA batteries, not included.
