There is a stand of short trees that I walk by every day on the U of I campus. Recently I noticed that these trees are covered in small, oblong pitted fruits that are just turning from yellow to bright red. I looked around online, and they look very much like photos of Cornelian Cherry. Are there any other fruit tree look-alikes (especially poisonous ones) that it could be? I would love to taste them, but not unless I am sure! What's the best way to know?
