Sometimes obsession pays off, as with this recipe -- a 21st century version of guvech, a classic Turkish stew, an homage of sorts to Mr. Pamuk. You can bake this for an hour in a covered casserole. You can also throw everything in a generous soup pot, clap the lid on it and cook it over high-ish heat atop the stove for 25 minutes and be done with it. Both ways work. No need to obsess about it.
*Should you find yourself harissaless, substitute a teaspoon red pepper flakes, 1 teaspoon coriander and 1 teaspoon caraway seeds and hope for the best.
