There is nothing better than fresh Montmorency cherries picked fresh from the tree. They are tart, but my 4 year-old and I will eat them straight up! We made a pie as well. Our drawf cherry tree doesn't produce a lot, but it gives us a nice taste.
I like to pit & freeze the cherries to use all winter. Usually, there are a few very kind souls who let me pick from their full-size trees.
