There is a certain pastry shop in Lisbon that I pass several times each day when I’m in that beautiful city. At some point, I decided to stop each time and try a new pastry. For research purposes, of course. Here is an interesting one. These travesseiros are puff pastry “pillows,” filled with almonds and custard and dusted with powdered sugar. One bite and the pastry shatters, showering the eater with both crumbs and sugar. A small price to pay for such rewarding homework.
