I made the Williams and Sonoma Pumpkin ice cream today. It had a great consistency after about 20 min in my ice cream maker (soft-serve consistency) so I put it in Tupperware in the freezer. Now it seems to be solid and I'm unable to scoop it without defrosting it. DId I do something wrong? I froze the freezer bowl of my ice cream maker for over 24 hours and I made the custard last night so it chilled overnight. Any other steps I could have forgotten or messed up? Thanks!
