These were delicious. I followed the directions for making in avdance, as well as blanching and slicing the mushrooms. I put it together, baked as directed. (It could have used either a longer time or a higher heat.) I served it with a mixed greens salad on the plate as pictured as a first course- it was perfect. I will definitely make these again.
These came out really great, but I definitely did not use that many mushrooms. I stuffed the pastries full and still only used about half a pound, not the 3/4 pound called for. That said, the tarts were delicious and seemed much fancier and more difficult than they actually were. They're a great appetizer, and a great light meal accompanied with a salad.
