I’ll be planting potatoes on St. Patrick’s Day and probably wearing something green. Alas, no Irish cheese board for dinner. My favorite Irish wheels—Gubbeen, Durrus, Coolea—are too hard to find these days. Their high prices make them slow movers at American cheese counters. But green cheese? I can do that. I adore this creamy feta dip, green from pistachios, cilantro and dill. You’ve seen it here before but I’m reprising it as a nod to the holiday and the imminent arrival of spring. I’ve heard raves from readers who’ve made it and hope you’ll soon join that club.
