- Preparation: 20 min
- Cooking: 480 min
- Makes: 1 serving (729 g)
- Difficulty: Hard
- Diets: Dairy-free, High protein
- Contains: egg, gluten, pork, soy
Ingredients
- 120 g Pork feet, raw
- 8 g Garlic, raw
- 6 g Ginger, fresh
- 75 g Egg noodles, dry
- 30 g Pork belly, raw
- 10 g Soy sauce
- 50 g Eggs, whole, raw
- 10 g Scallions, raw
- 420 g Water
Method
- Blanch the pork trotters in boiling water for 5 minutes to remove impurities, then drain and rinse well.
- Return the trotters to a clean pot with the garlic, ginger and about 420 g water for one bowl (enough to cover generously; scale up proportionally, roughly 2-2.5 L per kg of trotters, if simmering a bigger pot for several bowls); bring to a boil, then simmer hard, uncovered, for 7-8 hours, topping up water as needed, until the broth turns rich, cloudy and milky-white.
- Separately, simmer the pork belly in a little of the broth with half the soy sauce for 45-60 minutes until tender, then slice.
- Soft-boil the egg for 6-7 minutes, cool in cold water, peel and halve.
- Strain the finished broth, season with the remaining soy sauce, and bring to a simmer; cook the noodles separately in boiling water until tender, then drain.
- Divide the noodles between bowls, ladle the hot broth over, and top with the sliced pork belly, soft-boiled egg and scallion.
