Traveling in Morocco 30-some years ago, I had eaten tagines — stews distinguished by being cooked in the pot of the same name — that I did not recall as involving any browning.
This method is described as “starting the tagine cold.” It involves heating the lamb gently along with spices and other aromatics, allowing the flavors to fully penetrate the meat. At that point it is covered and cooked until tender.
When I tried the “cold start” approach, substituting a low heating of the lamb with aromatics and a little butter for the usual hard sear in olive oil, it worked like (well, kind of like) magic. The overall flavor of the dish was less robust than one that began with browning, but it was equally flavorful, in a gentler way.
In a Dutch oven or other large, heavy-bottomed pot, melt the butter over medium-low heat. Add the lamb, onion, garlic, pepper, salt, cinnamon, coriander, cumin, red pepper flakes, apricot preserves and vinegar and cook, stirring frequently, until the aroma of the spices is strong, about 5 to 7 minutes. (Do not allow the meat to brown.)
03Add chickpeas and stock, bring just to a simmer, then reduce the heat to low, cover and simmer gently until the lamb is very tender, about 1 hour 15 minutes.
04Add the raisins and continue to cook, uncovered, until they are nicely plumped, about 10 minutes more. Remove from heat, stir in the parsley and lemon juice, and serve with couscous.
