Verjus, the Lemon/Vinegar Alternative

We're hearing more about the increasing popularity of Verjus or Verjuice, a sour, acidic juice extracted from unripened grapes.  Popular in the Middle Ages, it fell out of favor, but is currently enjoying a revival.  Typically, it is used wherever you might use lemon juice or vinegar and we hear it makes a great sorbet. 

We're looking forward to experimenting with this old/new ingredient and reporting back to you.
