Verjus Sorbet with Poached Peaches

Verjus is a flavoring ingredient—much like vinegar—that was popular in the Middle Ages, but has only in this decade become more well known in the United States. The word derives from vertjus, or “green juice”, and refers to the juice of unripe grapes. It’s a fruity, acidic liquid that lends itself naturally to sorbets. You can use a variety of fruits in this dessert, but because the sorbet is very tart, the fruit should be very sweet.
