Mike's Pastry is an extremely popular bakery in Boston's North End (the line runs out the door after dinner on the weekends). While they have great cannolis, impressive butter cookies, and beautiful marzipan items, their pistachio macaroons are a hidden gem.
Some may find them a little too sweet or too rich (two things I've never experienced), but these things are amazing. They are covered in powdered sugar, the outside is just barely crunchy, the inside is chewy, almond-infused, and spotted with pistachios. Next time you're grabbing a cannoli, make sure you pick up a few of these cookies as well.
