Weight Watchers, very tasty Tagine.
Why is the meat tough even though the liquid is simmering? Halfway through braising lean cuts like cubed lamb steak, cooks often panic when the proteins seize up. Lean meat lacks the internal collagen found in shoulder cuts. Without intramuscular fat to melt into the sauce, direct heat over five minutes during the initial browning stage must be strictly controlled. Stir constantly over medium-low heat until the exterior turns greyish-brown without scorching the garlic.
Adding a full litre of boiling water creates a deep braising environment. Simmer uncovered or partially covered for forty minutes to allow the starches from the dried apricots and sultanas to dissolve into the liquid. This natural sugar release thickens the sauce without needing flour or cornstarch slurry. Watch the pan closely at the thirty-minute mark. If the liquid reduces too fast, lower the burner temperature immediately.
