This tiny Belmont shop specializes in the macaron, France’s ethereal, melt-in-the-mouth sandwich cookie of baked meringue in a rainbow of pastel colors and fantastical flavors of candies, fruits, nuts and flowers. They’re exceptionally beautiful, making an impressive if pricey gift in Praliné’s handsome boxes. Beyond macarons, there’s a typically indulgent assortment of patisserie standards like éclairs, cream puffs and elaborate tortes. Praliné is a museum of high art rendered in butter, eggs, flour and sugar.
