Howard Nakae specializes in growing the rare Hyakume persimmon, but he also has a few gnarled Hachiya trees in his orchard, which he thinks were planted almost 100 years ago. This recipe is from his first wife, Spring, as redacted by his daughter, Sheila, who helps run the farm and packing shed. For the pulp, peel persimmons, then process them in a food mill or puree in a food processor.
