Shibui
Benincasa hispida | White Gourd
Botanical Description
A trailing vine in the gourd family, Tōgan produces large, oblong fruits with a waxy, pale green to whitish rind. Despite its name, “winter melon” is typically harvested in summer and autumn and stored through the winter. The gourd’s flesh is mild, cooling, and moistening—perfect for Okinawa’s hot climate and traditionally used to balance heat and inflammation.
