Yes, you're right, this is a picture of potatoes. And why? I remember that on "Good Friday" of each year, my Grandma Barta would be in her garden planting potatoes. Why that date? That was just the day you were suppose to plant those potatoes. Did my Great-Grandmother plant her potatoes on "Good Friday"? I bet she did... And as regular as clockwork my Grandma would plant her potatoes on "Good Friday" and she would grow great crops of potatoes year after year.
