Take a large pan and briefly bake the garlic. It can color a little bit but shouldn't become brown. Add the stock, the water, the coconut aminos, herbs and spices
Bruise the galangal and the lemon grass and add to the pan. Leave to simmer slowly for about half an hour. Taste and add seasoning where needed.
Heat the butter in a frying pan and bake the mushrooms with spices of your choice until cooked. Set aside. Turn the heat up and add some oil to the pan. Bake the pork belly cubes until nice and crispy. Leave to drain on kitchen paper.
Cook the noodles in the meantime. Once your stock is up to taste, build your bowls. Place four bowls and add the cooked noodles.
Pour the hot broth on top and place the mushrooms, spring onions and the crispy pork belly on top. Add the broccoli cress and pour over a little hoisin sauce. Eat right away.
