Rinse veal meat well and pat dry. Add spices (coriander powder, garam masala, Kashmiri Lal Mirch, red chili powder and Kosher salt). Mix spices to combine with meat. Now add freshly squeezed lemon juice, papaya paste and fresh ginger + garlic paste. Mix to combine and massage meat with seasonings for 4-5 minutes. Cover and refrigerate overnight.
Remove meat from fridge after marination and let rest at room temperature. In a food processor, combine fried onions and yogurt to make a smooth mixture. Add fried onion/yogurt mixture to meat and mix to combine. Massage into meat for 1-2 minutes.
Preheat oven to 375 degrees Fahrenheit.
Dry roast grated coconut, slivered almonds and poppy seeds (in separate batches) until aromatic, careful not to burn. Add roasted nuts into a grinder and blend into a fine, smooth paste (I added a few tablespoons of water, as needed while grinding). *I pulsed this mixture in grinder/Ninja for at least 2-3 minutes, mixing as needed and pulsing again.
Add nut paste to marinated meat and mix again to combine all ingredients well (massage meat with all ingredients for another 2-3 minutes). Add ¼ cup Canola oil and mix to combine. *I use the same oil I fried the onions in.
Decrease oven setting to 350 degrees Fahrenheit. Place marinated meat in a heavy bottom baking dish/pot, cover to fully seal and bake marinated meat for 60 minutes, stirring 1-2 times in between, as needed.
After one hour, remove baking dish from oven, uncover and give coal smoke (carefully place heated coal in a tin foil container or aluminum foil and in center of meat, add 2 tsp of ghee and cover dish for 2-3 minutes. Now remove container/foil with coal, add freshly chopped coriander leaves, mint and green chili peppers, increase oven to 375 degrees Fahrenheit and bake for a final 5-7 minutes until liquid evaporates and oil separates.
