Heat coconut oil in a large heavy pot over medium-high heat. Season ribs with salt, brown well on all sides, about 8–10 minutes total. Set aside.
In the same pot, sauté onion 5 minutes until softened.
Add garlic and ginger, cook 1 minute.
Whisk in tamarind paste, coconut milk, and broth, scraping up any browned bits.
Return ribs to the pot, nestling them into the liquid.
Bring to a simmer, cover, and cook 1 hour 45 minutes to 2 hours until the meat is completely fork- tender and pulling from the bone.
Season with salt, top with cilantro, and serve hot.
