Dry beef salad

Dry beef salad! Oh my god, one of the best snack ever. Just look at the picture, isn't it so delicious?
The best place to eat this (it's called Nộm thịt bò) is Hồ Hoàn Kiếm street, the shortest street of Hanoi. It's only, what, i dont know but very very short. Maybe it takes about 2 minutes to walk from one end to the other. A special street for the best snack. Yummy.
I've never tried to make it, there must be some secret process but it seems really easy, just put everything on the dish and pour mixed fish sauce on.
The first layer is green papaya and carrot sliced really small like thread. On top of it is spices like mint, basil and some other leaves. Then the layer of dry beef. The Vietnamese dry beef is not smoked, they sun dry it somehow, so the beef is not too dry, but tough bit and chewy. It tastes kinda sweet, salty and spicy, and just irresistable (especially when you squeeze lemon juice on it). Along with the dry beef is buttery smashed peanut.
Maybe the secret of Nộm thịt bò lies in the fish sauce mixed with vinegar, water, sugar, chili... The sauce has to be salty enough to eat with the dish, but not too salty so we can drink it after finishing all the vegetable and meat. Anyway, this is one of the best snack ever ever ever.
