Ingredients

Why this recipe works

Slow cooking transforms tough lamb shoulder into melt-in-your-mouth pieces. The low, gentle heat breaks down collagen and connective tissue, yielding meat that is fork-tender and deeply flavorful. Meanwhile, the spiced tomato-ginger puree reduces and thickens, concentrating its flavors into a rich, complex sauce.

The combination of yogurt and garlic herb butter adds richness and tang, balancing the warm spices. Yogurt also helps tenderize the meat as it cooks, while the butter lends a glossy finish and silky mouthfeel.

Because everything cooks together, the flavors meld and deepen over hours, creating a curry that tastes far more complex than the sum of its parts.

Notes and substitutions

Choose well-marbled lamb shoulder for the best results; it becomes meltingly tender during the long cook time. The spiced tomato-ginger makhani puree can be store-bought or homemade.

If using store-bought, look for a quality brand with warm spices like garam masala and cumin. Minced garlic adds pungency, and Greek yogurt provides tang and creaminess.

Garlic herb butter is the finishing touch — cut it into medallions so it melts evenly into the sauce. You can use plain butter with a pinch of dried herbs if needed. The recipe calls for a 6-quart slow cooker; any similar size works. For a thicker sauce, remove the lid during the last 30 minutes of cooking to let excess moisture evaporate.

• lamb shoulder: beef chuck, cut into 1-inch cubes (cook until fork-tender, about 8 hours on low)
