Two consecutive, cold Fridays, while the children were in school, I found myself luring willing diners to Al di La Trattoria in Park Slope just to eat the same dish. For some, comfort food is a bowl of mashed potatoes, a hamburger or ice cream maybe; for me, this restaurant’s version of polenta ai funghi hits the spot. The warm, gooey, not-too-cheesy polenta is draped with vibrant kale and a tumble of braised wild mushrooms. It is deliciously unctuous – filling but not overly so. It’s the kind of comfort food you really want your lunch partner to taste, but not really! With snow falling and Friday just around the corner, I may make it a polenta ai funghi trifecta.
