Fermented cranberry relish

I had cranberries left from Christmas, so I made some cranberry/orange/pecan salad...and decided to ferment it, to add some probiotics. The recipe to leave it on the counter for no longer than 3 days or it will start to develop alcohol. I tasted it the first two days..nothing...this morning they were leaking, so I knew they had started to ferment...omg...it tastes like cranberry orange wine, only crunchy. It definitely has alcohol in it...wonder what proof it is??? Think I'll try some blackberries next!
