Kalo root is a plant used in cooking food.

In 2370, Gideon Seyetik served senior staff of Deep Space 9 a dinner of his creation made with seared Kalo roots layered over slices of roasted Waroon, Rumall stock, Gremish, Vulcan redspice, Humat pods, ice salt, and pepper. The recipe took years to perfect, and Chief O'Brien wanted a copy. (DS9: "Second Sight")
