Thanks all, good tips. I'll look for pie pumpkin or maybe even butternut squash? Good thing I asked, I probably would of ended up with one of the big monstrosities they sell at the side of the road
I did a bit of reading and I guess the major difference between can and fresh is that there is more water in the fresh. The late addition of puree sounds like a interesting idea, any idea on how much you put in? I suppose I could get a bigger pie pumpkin and hold back a couple cups until the end.
I'll be doing straight BIAB, so I don't think rice hulls will be needed.
