Instructions

1. For Curry Powder - Finely grind all the spices together in a spice grinder. Store tightly covered for up to 3 months.
2. For Beef and Tendon - Mix 8 cups water and 3 tablespoons of the salt in a large container until the salt dissolves. Add the tendons and soak for 12 hours. Drain, discarding the water and setting the tendons aside.
3. Bring a large pot of water to a boil over high heat. Blanch the tendons for 5 minutes, then drain, discarding the water. Return the tendons to the pot along with 1 tablespoon of the salt, 1 tablespoon of the cane vinegar, and a third each of the onions, garlic, and ginger. Cover with fresh water. Bring to a boil over high heat, then lower the heat to maintain a simmer and cook, covered, for 2 hours. Drain and set the tendons aside.
4. Preheat the oven to 375°F. Mix the remaining 2 tablespoons salt, 2 tablespoons of the cane vinegar, and 2 tablespoons of the curry powder and rub all over the chuck roast.
5. Heat the oil in a large Dutch oven over medium- high heat. Add the beef and sear until golden brown on each side, about 5 minutes per side. Remove the beef from the pan and add the remaining onions, garlic, and ginger and cook until the vegetables start to caramelize, about 5 minutes. Mix the remaining 2 tablespoons curry powder with 2 tablespoons of the cane vinegar, add to the pan, and stir until fragrant, about 1 minute. Add the stock and stir well. Nestle the beef and tendons back into the pot and bring to a boil. Cover the pot, transfer to the preheated oven, and braise until tender when pierced with a chopstick, about 2?1?2 hours. When done, remove from the oven and let cool for at least 3 hours, or overnight.
6. When cooled, remove the beef and tendons and set aside. Remove the solidified fat and ginger slices and discard. Puree the sauce with an immersion blender until smooth. Cut the beef into rough 2-inch pieces and cut the tendon crosswise into 1?4-inch slices. Return, evenly dispersed, to the pot, along with the daikon.
7. Bring to a simmer over medium-high heat. Cook until the meat is heated through and the sauce has a nice unctuous texture, about 5 to 10 minutes. Season to taste with salt and the remaining 1 tablespoon cane vinegar, remove from the heat, and generously top with the garnishes. Serve with rice or crusty rolls.
