Until recently, dill was an underappreciated herb in our garden. We would mostly grow it for its delicate structure and because it was a favorite of the swallowtail butterfly caterpillars. It wasn’t until we had dill in a cream sauce with chicken, accented by a touch of mustard, that we started making sure we grew enough for the caterpillars and ourselves. Take that creamed dill chicken and encase it in puff pastry for a potpie, and it becomes perfect comfort food. Over the winter, grow some dill in your windowsill, or if you are lucky enough to live in a temperate area like Southern California, make sure to grow dill in the cool months. But be forewarned: You may find yourself addicted.
