In Peru, when you're hunting for sweets for your sweet, chances are you'll bring home a floaty meringue-topped custard called Suspiro de Limeña — it translates to "the sigh of a woman" — or maybe a box of rich pioninos, rolled caramel cakes filled with dulce de leche. Not headed for Lima anytime soon? Drop by Marjorie Silva's Azucar Bakery, where rich flan and other traditional desserts of her native country sit side by side with the chocolate and red-velvet cakes you expect to find in an American bakery.
