The list of desserts I like is lengthy, but semifreddo is definitely one I could have on a weekly basis. Semifreddo (translation: half-cold) is a partially frozen dessert, often, as in the accompanying recipe, made by folding meringue into a flavored base that's then chilled. The result is a light, almost ethereal dessert that doesn't overwhelm. It's the perfect ending for a heavy meal, especially when it's warm out.

This recipe is inspired by Key lime pie—it starts with tart limes, gets sweetened with condensed milk, then you add super-glossy, billowing Italian meringue. A salty, crunchy pretzel crust provides a nice textural contrast and makes the lime flavor pop.
