Parboil the potatoes
In a blender put sliced ginger, shallots, and a tablespoon of oil
Crush the lemongrass so that it releases the flavor more
Set the instant pot to saute and when hot add 1 tablespoon olive oil
Cook the meat in big slabs (see picture) for about 2-3 minutes on each side
Add the ginger and shallots that you blitzed into the instant pot and cook them out for 3 minutes stirring well
Put in all the other spices and stir
Put in the coconut milk and stir
Put in 6 cups of water and stir well
Put back the beef slabs
Add in the lemon juice, celery, carrot spring onion, crushed bay leaves, crushed kafir lime leaves.
Pressure cook for 30 minutes and 10 minutes natural release
Take out the meat
Taste the broth - and add salt and pepper and sugar ketchup manis to taste.
Sautee the potatoes and cut into big slabs
Cut the meat also into good-sized chunks
And then add to a soup bowl - then meat, potatoes plus the soup broth.
If you want to make this - then blitz 2 chillis in the blender with some oil - and add sparingly to taste into your own personal bowl (not the whole bowl of soup)
