Method:-
Heat a little of the oil in a large pan and brown the beef in batches, removing to a plate after, reserving any juices.
Meanwhile, in a mini chopper or food processor, whizz half the coriander, the chopped lemongrass, garlic, chillies, spring onion, salt and galangal with the rest of the oil until you have a rough paste.
Add the paste to a frying pan and cook for a few mins, then add the beef and all the remaining ingredients, apart from the remaining coriander and lime juice.
Make sure there is enough liquid and simmer for 3 hours or until the meat is cooked.
If the sauce is too thin, strain it off and boil it to reduce.
Stir in the remaining coriander and lime juice, then season with more fish sauce or sugar or salt as needed.
