In a dish, soak a slice of white bread, crusts and all, in around 2 tablespoons of milk or as needed; just enough to cover it.
Using a mortar and pestle, pound the garlic cloves and knob of ginger into a paste, then transfer to a mixing bowl, along with the fatty pork mince, soaked bread, salt, white pepper, and tablespoon of finely chopped fresh coriander, basil, dill or other Southeast Asian herbs of your choice. Combine well then refrigerate until ready to use.
Pound the other knob of ginger and lemongrass in the mortar and pestle just until they break and their aromas are released.
To a medium-sized soup pot over high heat, add the litre of stock, ginger and lemongrass, bring to a boil, then turn the heat to low and simmer.
While the soup is simmering, boil the eggs until jammy-soft (around 5 minutes – follow our guide to boiling perfect soft-boiled eggs) then transfer to a cold bowl of water and set aside.
Remove the pork mince mixture from the fridge and form the seasoned pork mince into mini meatballs: use a teaspoon to scoop out the mince, roll it between two hands a few times to shape into a rough small meatball of around 3cm in diameter (don’t over-roll), place it on a plate, and repeat.
Once you’ve finished making all the meatballs, increase the soup heat again, and gently submerge each meatball into the soup. Reduce the heat, add the carrot slices, and simmer for 10 minutes.
A few more minutes before you are reading to serve, add the rice noodles and stir to combine well, then ladle the noodle soup between bowls, arrange the meatballs, carrots and bok choy/lettuce on top, submerging the latter so it ‘cooks’.
Peel the eggs beside the bowls, and carefully slice each egg in half over the bowl where you intend to place the egg, so any soft runny yolk drips onto the noodles and not on your cutting board.
Sprinkle each bowl of noodles with finely sliced garlic chives and chilli flakes, and serve with fresh aromatic herbs, and condiments, such as chilli oil, fresh sliced red chillies, fish sauce, Sriracha sauce, crispy fried shallots, and crunchy fried garlic.
