Three cheers for a new way to make chicken soup Using the parmesan rind to flavor the broth is one of those amazing kitchen tricks that isnt just an ace-in-the-hole for complex flavor, it also stretch an ingredients use further. This recipe includes a homemade almond and herb pesto, however if you want to cut down on time, a high-quality store-bought pesto will work well. Taste before dolloping on the soupsome store-bought pestos can benefit from a squeeze of lemon juice.
