[Request] I have 30kg of pumpking / winter squash, what do I do?

So I harvested my pumpkins today and made pumpkin salvia risotto (used 500g of pumpkin). Now I'm looking for recipes to preserve the rest of it, like jams, chutneys, pickles, etc. I don't mind pumpkin pancakes or pies, but I cant eat 30kg worth of them... Thanks in advance
