Like any worthwhile relationship, Littlenecks with Fava Pod Pesto has its easy bits and its tricky parts.  The easy bits are the littlenecks. Lord knows, they seem to shoulder their way onto our blog with yet another clam recipe–Pick me! Pick me!–every three months or so.  There’s a reason we eat them so often – no prep to speak of, and they share.  Coax them open with a little heat and they leak their ambrosial juices into whatever else is in the pan.
