Heat 1 tablespoon vegetable oil (or chili oil) in a saucepan over medium-high heat. Add 1 tablespoon finely diced ginger, 1 tablespoon finely diced garlic, 2 Thai chilli peppers (sliced), and 3 sticks lemongrass (cut into small pieces). Cook for 2 minutes until fragrant.
Pour in 1.5 liters chicken broth. Add 1 small can coconut milk. Bring to a boil.
Add 1 tablespoon freshly chopped coriander. Season with Asia-Thai spice mixture and juice from 1 lime to taste. The broth can be prepared up to 1 day ahead and refrigerated.
Blanch broccoli florets in boiling water for 3 minutes, then drain. Blanch sugar snap peas for 2 minutes, then drain. Cook Chinese egg noodles (Mie noodles) in water according to package directions, then drain.
Cut pork loin into bite-sized pieces. Cut turkey schnitzel and salmon fillets into bite-sized pieces. Quarter the brown mushrooms. Refrigerate all raw proteins until serving time.
Pour the prepared broth into a fondue pot and keep simmering over a rechaud (tabletop heater). Arrange soy sauce, chili sauce, sweet and sour sauce, and peanut sauce in separate small bowls. Arrange all proteins, vegetables, noodles, and mushrooms on a platter around the fondue pot.
Using fondue forks, spear pieces of food or pack them into wire baskets. Dip into the simmering broth: noodles and vegetables for 1-2 minutes, fish for 1-2 minutes, prawns for 2-3 minutes, pork for 2-3 minutes until it reaches 63°C (145°F), and poultry for 3-4 minutes until it reaches 74°C (165°F).
Remove cooked food and dip in your choice of sauce before eating.
