I first had these at my first married "grown up" party, newly-wed and going to hubby's work party. I was 19 years old, and scared to death! But these treats were delicious and led to a conversation with the boss's wife about different varieties of mushrooms....these definitely eased my way into the scary grown-up world! Usually, Palmiers are a sweet treat. Instead, this is a delicious appetizer, and is really unique, in that they turn out in a figure 8. The steam created by the moisture in the butter and mushrooms causes the dough to puff, making this flaky pastry even more flaky! Prep time does not include thawing time for the pastry sheets, but does include the chilling time!
