Heat the oil in a 6-quart stockpot over medium-high heat to make the broth. Add onion; cook and stir for 3 minutes or until tender. Add ginger, garlic powder, brown sugar, soy sauce, curry paste, and stock. Heat to a boil. Lower the heat to a simmer for 20 minutes while covered. Just before serving, stir the lime juice into the soup.
Give visitors the option to customize their meal by arranging meats, veggies, noodles, and garnishes in bowls or on plates.
Depending on whether you're serving one broth or two distinct broths, pour broth into one or both sides of the boiling pot when ready to serve. Ladle the broth over rice or noodles once the veggies and meats have been cooked.
REMEMBER: Pressure cooker or Instant Pot Method
Method of Multifunction Electric Pressure Cooker (Reduces Cooking Time by One Hour): In the pot of the multipurpose electric pressure cooker, heat the oil on the medium sauté setting (instant pot). Add onion; cook and stir for 3 minutes or until tender. Add ginger, garlic powder, brown sugar, soy sauce, curry paste, and stock. Put on the lid and secure it. Put the pot on high pressure (or soup setting) and cook for 10 minutes. Before opening, release the pressure in the pot and carefully remove the lid. (For details on safe operation, consult the manufacturer's handbook.) Put the sauté setting on low. Add lime juice and mix. Permit visitors to cook steak in broth for two to three minutes, or until done to their liking. Make each bowl unique, then serve as instructed.
