This made a very nice, out-of-the-ordinary dinner. The pastry was excellent; I wouldn't change anything about it. For the mushroom sauce, we added some extra seasoning (paprika, garlic, and some basil) and we used more fresh tarragon than the recipe called for. The flavor was great, and the aroma in the kitchen was phenomenal. However, we thought the finished product was a little gummy...next time we make it, we're going to leave out half the flour and see if that helps. Overall, this was a really good recipe, and the presentation was very impressive (I wish I'd had a camera handy!). Thanks for posting.
