The surprise Acorn Squash mutant...

[MiHale]

7. Yes you did...

Exactly… we’ll see what the big ones bring.
Talking to a friend the other day about what to do with’em…surprise! …Make flour.
She’s Amish has a farm and greenhouse down the way. You can either peel or not but what you do is break down the squash by grater, food processor or whatever…the idea is to get the pieces small so they can dehydrate completely. She grates and sun dries hers. Then after drying process into a fine powder. You can use any squash.

I found a link that explains it as well as she did plus a little more.
