Nangoku Seika Suishatei (Mizukurumaya) Salt Kenpi 1kg, Value Pack The salt enhances the sweetness, resulting in a less sweet flavor. This product is so addictive, you won't be able to stop once you start eating it! Domestic (Miyazaki Prefecture) sweet potatoes are cut into thin strips and shaped into kenpi, then immediately fried slowly in a custom-blended cooking oil. The frying time and temperature are key to bringing out the sweet potato's vibrant color. After drying, the surface is coated with a syrup made from Kochi Prefecture Muroto deep-sea water salt and sugar. The exquisite harmony of the sweet potato's sweetness and the salt's umami makes it irresistibly delicious. The salt also helps the sugar penetrate, resulting in a crispy exterior and a moderately soft interior.
