6 tablespoons vegetable oil
½ teaspoon whole cloves
16 cardamom pods
2 inches cinnamon sticks
10 black peppercorns

Garnish:

1 ounce blanched split almonds or 1 ounce slivered almonds

Equipment Needed

Blender or food processor
Baking dish (stainless steel or glass recommended)
Small pan
Lid for baking dish or aluminum foil

Instructions

Begin by preparing the leg of lamb. Remove all the excess fat and the thin, white skin (silverskin) from the outside of the leg. Alternatively, ask your butcher to do this for you. This step ensures the marinade penetrates the meat effectively.
Place the prepared leg of lamb in your baking dish. Stainless steel or glass dishes are preferable when working with yogurt marinades, as they are less reactive than other materials.
Now, create the flavorful yogurt paste. In your blender or food processor, combine the blanched almonds, coarsely chopped onions, peeled garlic cloves, peeled and coarsely chopped ginger, coarsely chopped green chilies, and approximately 3 tablespoons of the plain yogurt. Process until you achieve a smooth paste. You may need to scrape down the sides of the blender occasionally to ensure even processing.
In a separate dish, combine the remaining yogurt. Beat it lightly until it is smooth and lump-free. Add the freshly made almond and spice paste, ground cumin, ground coriander, cayenne pepper, and garam masala. Mix well to ensure all the spices are evenly distributed throughout the yogurt.
Using a sharp knife, stab the lamb leg all over, making good, deep cuts. These cuts will allow the marinade to penetrate deep into the meat, infusing it with flavor from the inside out.
The next step is crucial for maximum flavor. Using your hands (or gloves if you prefer), generously push the yogurt paste into the natural openings of the lamb, then into the cuts you made. Ensure the paste is packed tightly into every nook and cranny.
Spread the remaining yogurt paste all over and around the lamb, coating it completely. The side of the lamb that will face up during baking should receive a particularly thick layer of the yogurt marinade.
Cover the baking dish tightly with a lid or tightly with aluminum foil. Refrigerate the marinated lamb for at least 24 hours. The longer it marinates, the more flavorful and tender the lamb will become.
When you are ready to bake the lamb, remove it from the refrigerator and allow it to sit at room temperature for at least 30-60 minutes. This will help the lamb cook more evenly.
Preheat your oven to 400 degrees F (200 degrees C).
While the oven preheats, heat the vegetable oil in a small pan over medium heat. When the oil is hot, add the whole cloves, cardamom pods, cinnamon sticks, and black peppercorns. Cook for a few seconds until the cloves swell and become fragrant. Be careful not to burn the spices. This step infuses the oil with aromatic flavors that will enhance the lamb.
Pour the hot, spiced oil over the lamb. The sizzling oil will further enhance the flavors of the marinade.
Cover the baking dish with its lid or tightly with aluminum foil. Bake the lamb covered for 1 hour and 30 minutes. The covering helps to keep the lamb moist and tender during the initial cooking process.
Remove the lid or foil and continue baking for another 45 minutes, or longer if you prefer your lamb well-done. During this time, baste the meat regularly with the accumulated sauce in the pan. Basting helps to keep the lamb moist and adds flavor.
Scatter the sultanas and blanched split almonds (or slivered almonds) over the top of the lamb in the yogurt paste. You can arrange them in a decorative pattern if desired.
Bake for another 5-6 minutes, or until the almonds are lightly toasted and golden brown.
Remove the dish from the oven and let the lamb rest in a warm place for about 15 minutes. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful final product.
Carefully remove the leg of lamb from the pan and place it on a serving platter. Spoon off any excess fat from the top of the sauce. Strain the sauce through a fine-mesh sieve to remove the whole spices, discarding the spices.
Serve the leg of lamb hot, with the strained sauce poured generously around it.

Expert Tips & Tricks

For a deeper, richer flavor, consider using smoked paprika in addition to or in place of the cayenne pepper.
If you don’t have a blender or food processor, you can finely chop the almonds, onions, garlic, ginger, and chilies by hand.
If the sauce becomes too thick during baking, add a little water or broth to thin it out.
To ensure the lamb is cooked to your liking, use a meat thermometer. For medium-rare, aim for an internal temperature of 130-135 degrees F; for medium, 135-140 degrees F; and for well-done, 145-150 degrees F.

Serving & Storage Suggestions

Serve this leg of lamb hot, garnished with fresh cilantro or mint, if desired. It pairs perfectly with basmati rice, naan bread, and a side of green vegetables such as spinach, green beans, or asparagus. Leftover lamb can be stored in an airtight container in the refrigerator for up to 3-4 days. Reheat gently in the oven or microwave. The sauce can also be stored separately and reheated. To freeze, wrap the lamb tightly in plastic wrap and then in foil. It can be frozen for up to 2-3 months. Thaw overnight in the refrigerator before reheating.

Variations & Substitutions

Dairy-Free: Substitute the plain yogurt with a plant-based yogurt alternative, such as coconut yogurt or almond yogurt. Be sure to choose an unsweetened variety.
Vegetarian Adaptation: While you can’t substitute the lamb itself, you can use this marinade on large portobello mushrooms or a hearty vegetable roast for a flavorful vegetarian main course.
Spice Level: Adjust the amount of green chilies and cayenne pepper to your preference. For a milder dish, remove the seeds from the chilies or use a milder variety.
Herb Infusion: Add fresh herbs like rosemary or thyme to the marinade for a different flavor profile.

FAQs (Frequently Asked Questions)

Q: Can I marinate the lamb for longer than 24 hours?
A: Yes, you can marinate the lamb for up to 48 hours for an even more intense flavor. Just ensure it’s properly refrigerated.

Q: Can I use dried chilies instead of fresh green chilies?
A: Yes, you can use dried red chilies, but soak them in hot water for about 30 minutes to soften them before blending them into the paste.

Q: What if I don’t have blanched almonds?
A: You can use regular almonds, but blanching them removes the skins and gives a smoother texture to the paste. To blanch, soak almonds in boiling water for a minute, then drain and rub off the skins.

Q: Can I use a different cut of lamb?
A: While this recipe is specifically for a leg of lamb, you could adapt it for a shoulder of lamb, but you may need to adjust the cooking time.

Q: The sauce is too spicy for me. How can I tone it down?
A: Add a tablespoon of honey or maple syrup to the sauce to balance the heat. A squeeze of lemon juice can also help cut through the spice.
