enough chicken broth to get it to the consistency that you want your soup to be. I would also saute some onion or/and leek add some carrots and seasonings that you like. Curry goes well with squash. I would then blend/puree all together. If your not watching your waistline you can add some cream or perhaps some coconut milk if your going with curry. I hope this gives you some ideas.
sorry, wrong key. Just freeze it and then defrost, mash with a
little unsalted butter, s&p and serve. It freezes really well. You can tart it up with a little rosemary or olive oil but this is gilding the lily. I wanted to buy some today, hard to find here, but it was $2.49 a pound in Whole Foods which is ridiculous.
