What did people do in the days before store-bought puff pastry? I'm guessing whipping up a nice apple strudel wasn't on the list that often. What did people serve at cocktail parties before Pepperidge Farm and Dufour made pinwheels and brie en croute so disastrously simple to make? Ok, sure, you can always make puff pastry from scratch, but now any yahoo with 20 minutes and a toaster oven can make buttery, flaky napoleons or upscale pigs in a blanket. It's the best thing to happen to amateur cooks since that cookie recipe was printed on the back of bags of Toll House chocolate chips.
