Hang some of those grapes where it's warm, dry, and dark; and make raisins. I've cut them in half so they dry faster, and run them through my dehydrator.
Here they only call them pump look ins if they're orange. The'd call this summer squash, but it Does bake well; whatever you call it! They also keep well in a root cellar, so very smart for winter food!
I love hazelnuts on Any form, LOL but fresh cracked is best.
You should take some cuttings home on the grapes, always nice to have some locals! I have wild grapes on the homestead, and hope to do some grafting with nicer grapes on some of the vines.
Like your pictures, they made me hungry! 🤠👍💙
