Look for one made with all butter instead of shortening. The best store-bought option I’ve tried is Dufour, which I usually find at Whole Foods. It bakes up golden brown in the oven, even without an egg wash, and tastes like the real deal. Trader Joe's also makes an all-butter puff pastry. That being said, when topped with buttery, spiced, brown sugar pear slices, and baked to golden perfection, just about any pastry will be delicious.
