Clean the oxtails using water and vinegar, then pat them dry thoroughly. Combine the brown sugar, soy sauce, Worcestershire sauce, salt, garlic powder, black pepper, allspice, and browning sauce in a bowl. Rub this mixture on the oxtails until fully coated.

Turn on your pressure cooker to Sauté setting. Once hot, pour in the oil. Lay the pieces of oxtail flat, leaving a little space between them, and sear both sides until browned. Transfer the browned pieces to a separate dish and set aside.

Scrape up any stuck-on bits in the pot by splashing in a bit of beef stock and stirring with a wooden spoon. Toss in the garlic, chopped yellow and green onions, habanero pepper, and carrots. Cook everything while stirring for about 5 minutes or until the onions soften.

Add thyme, the browned oxtails (along with any leftover marinade), ketchup, and the rest of the beef broth to the pressure cooker. Exit Sauté mode, lock on the lid, and set it to cook under high pressure for 45 minutes. Let the pressure drop on its own after cooking.

After the pressure releases, take out the oxtails and veggies, leaving the liquid behind in the pot. Switch back to Saute mode. Stir together cornstarch and water in a small bowl to make a slurry, then add it to the pot. Drop in the rinsed butter beans and simmer for about 5 minutes, letting the sauce reduce and thicken slightly.

Carefully return the oxtails and veggies to the pot, stirring gently so the sauce covers everything. Dish it out while it's hot and dig in!
