First fruit of the season picked. The fruit must be a bright yellow with minimum green showing for the best flavor, also if slightly green the fruit has an unpleasant taste. I eat them raw and about 20 makes a fine snack. Cooked they are most delicious, and they make a fine pie almost peach in taste. There are three plants in the patch, and they spread extensively.
