Sweet potato (Gorojima Kintoki)

There is a lot of sweet potato cultivation in Ishikawa Prefecture: Gorojima-kintoki in the sand dune area of Kanazawa City, Kahokkuri in Kahoku City, Noto-kintoki, which is certified as a Noto vegetable, etc. Gorojima-kintoki, one of the official Kaga Vegetables, is a “brand-name sweet potato” variety that is known all over Japan for its glossy appearance and sweetness. On a quality-over-quantity basis, less fertilizer is applied in order to increase the starch content of the potato. Thus, Gorojima-kintoki is characterized by its high sugar content and low moisture. It is also suitable for processing; sweets, soft ice cream, distilled liquor and other products have been developed. When cooking, adding heat slowly increases sweetness.
