For various reasons, life had left me with a pound of dried chickpeas in my pantry and a 5-pound hunk of lamb shoulder in my chest freezer, and I vaguely recalled that there was a famous lamb and chickpeas recipe making the rounds. It turns out my mother-in-law had adapted it from The Zahav Lamb Shoulder. But even the adaptation was a little complicated for me, so I tried to streamline further.
Step one: Dry-brine
Take one big hunk of boneless shoulder (bone-in would be fine, I'm sure), mine was five pounds. Rub on 4 tablespoons of salt, 2 teaspoons of black pepper, ground fennel, ground allspice, and minced or powdered garlic. Let it sit covered in your fridge for at least 24 hours. It will start to get stinky, funky, and a little funny-looking, but in a good way.
Step two: Slow-cook
Put lamb shoulder, dried chickpeas, and 8 cups of water plus 1/2 cup pomegranate molasses in your slow-cooker for approximately 9-10 hours. In my case, that actually overfilled my Instantpot, so I siphoned out about two cups of braising liquid and it was all fine. Not sure what the correct amount of liquid is.
Step three: Shellac
Preheat your oven to 500 degrees. Take out the lamb, which at this point should fall apart in your tongs, and put it in a roasting pan. Brush it with a couple more tablespoons of pomegranate molasses and a couple more tablespoons of the braising liquid, for about 30 minutes. Re-baste/brush 1-2 times in there if you can.
Meanwhile, drain off all the liquid from your chickpeas and skim off the fat. I use this fat separator, a great new kitchen gadget via Megan McCardle. If you don't have a fat separator you can do more cumbersome things like chill the whole dish and peel off the fat, but ugh, why? If you have a slow-cooker, buy a fat separator.
Then add some of the liquid back to the chickpeas, pour some of it on the lamb, and use the rest for some other delicious project.
Step four: Serve
Rich unctuous chickpeas, crispy-tender lamb, and whatever else you want. I supplied a tomato-cucumber salad, challah from Masa Madre and a hot sauce made of equal parts Cholula and Belazu Smoked Harissa. YMMV.
