Heat butter & olive oil on medium-high. Brown lamb on all sides. Set aside.
Sauté diced onion, celery, carrots & green onions, til soft.
Spread 1 tbsp of honey all over the leg of lamb.
Add spice rub of choice all over the lamb (I used garam masala + cinnamon)
Add a piece of ginger & 10-12 unpeeled garlic cloves. Deglaze with 1 cup of white wine.
Add thyme, rosemary, bay leaf and salt.
Place lamb on top, add 1/2 cup white wine + broth half-way up the meat. Cover and cook 7 hours in the oven at 230°F
It's ready! Meat so tender you can eat it with a spoon!
