I've been very lucky. I learned to make spanakopita, the Greek spinach and feta casserole encased in filo dough, from a variety of sources — even without the benefit of a Greek grandmother by my side. I had books, I had friends, and eventually, I had professional cooks show me. I've also spent a lifetime eating it and enjoying every bite in diners, upscale restaurants, and yes, versions made by someone else's loving Greek grandmother.
I noticed a few key things along the way, learned lessons from trial and error, and have modified my recipe over the years to create a fail-proof pie (it's all in how you fold it), with a filling so rich and flavorful you'll wonder why you waited so long to make this a part of your home-cooking repertoire.
