I've just had an ice cream & puff pastry epiphane!
Holy crap. I got some blueberry ice cream from Trader Joe's the other day. Had some puff pastry shells sitting in my freezer. Decided that maybe stuffing a warm puff pastry shell with the creamy blueberry ice cream might be a good idea.
It was a brilliant idea! Well, I didn't eat a whole shell but I did make a mini ice cream sandwich with the warm puff pastry shell tops that I cut out. (Trying to watch my waistline). However, I stuffed and distributed the six blueberry ice cream stuffed warm puff pastry shells to my co-workers and they were mightily well received.
Do try it. You might even yell oh my god like in your small work corner kitchen like I did.
