Our friends Steve and Alesandra brought a big bowl of creme fraiche to our pie extravaganza and it was delicious! Surprisingly, hardly anyone had any. ( maybe it was the 15 pies to choose from) We ended up with lots of leftovers and I didn’t know what to do with it. Molly’s friend Juliette suggested using it in place of sour cream in this sour cream ice cream recipe. The result was fantastic! Rich and creamy with a tangy finish. Yum. Thanks everyone for your ingredients and suggestions.
