I like the freezing idea and may try that this year. In the past I've dried them in the oven on low, then I got a dehydrator and that works well too. Dry em out, put them in plastic bags and keep them in the cupboard, they keep all year (at least I think so, dont think I've ever had a batch last a year).
When you're ready to use, rehydrate. I like red wine because I'm generally going to fry them up for alongside some venison steak and red wine goes pretty darn well with the two but water or chicken stock work too.
I like the freezing idea though because you can fry them up like fresh. Thanks!
