A Japanese tomato salted and ready to be eaten. The confusion about ‘fruits’ and ‘vegetables’ arises because of the differences in usage between scientists and cooks. Scientifically speaking, a tomato is definitely a fruit, developed from the ovary in the base of the flower, and containing the seeds of the plant. This is a typical tomato found in Japan during the spring, featuring a tough skin that resists cracks. These are sweet and crunchy and best served on their own.
