Mushroom Palmiers

I found this recipe while working at a small-town museum in West Texas. It was the appetizer for a fundraiser a long, long time ago, and it’s still a huge hit at parties. Frozen puff pastry helps make it easy and impressive. The palmiers freeze well too. —Judy Lock, Panhandle, Texas
