Slice onion into thin slice and marinate in sugar and vinegar for 15 mins, then squeeze out excess juice. Chop rau răm and fried shallots. Fry beef in a pan over high heat until golden but still rare in the center (like a steak). Afterwards, slice beef into thin slices and marinate with fish sauce, and lime juice and sugar (all flavors should be even) for 15 mins.
