I made this yesterday with a huge (2.3#), incredibly ripe wheel of brie and all those dried wild mushrooms. Easy and really good recipe! We also did not have Burgundy with it; we had Chinon and Saumur-Champigny.
Anyway, it is an easy recipe but there was nothing easy about what I did: Firstly, that huge cheese only just barely fit in the puff pastry, even with considerable rolling-out. You are warned not to stretch the pastry when wrapping it, though the recipe doesn't say why. Well, I had to... and the reason why is that the weakened pastry will tear during the cooking and melted cheese flows all over the baking sheet.
And then there are -- were!
-- those dried wild mushrooms. I had bought a few ounces each of black trumpets and mousserons some time ago. I had read that they grew in sandy soil but jeez louise: The first meal I made, I figured I'd just give them a couple rinses and that would be that. Nope. Plenty of grit made it into the sauce; I had to throw it out. I was determined to use up all of the remaining mushrooms in one go when I had the time to clean them. This recipe was going to be it.
Fifteen waters.
And I found debris: grit, leaves, twigs, you name it. Ugh. The were good but they weren't that good.
But I can see how a normal size wheel with normal mushrooms this would be totally groovy.
