Chimichurri

This is the traditional sauce, essential accompaniment of any
Argentinean BBQ. Its famous for the fact that there are as many recipes
as there are cooks!

Recipe:

chopped garlic
parsley
oregano
grounded cumin
basil
olive oil
lemon juice
vinegar
salt
black pepper
hot chillies

Preferably (as with everything!) use fresh and quality ingredients.
Finely chop the garlic, parsley, oregano and basil, then mix with oil,
lemon juice, a bit of salt (not much, because the meat and chorizos
should be salted), grounded cumin, black pepper and vinegar.
Let it marinate for a few days (the longer the better).
The proportions of the ingredients is for you to experiment and find your way!

Etymology of the word "Chimichurri"

According to oral tradition, this word derive from the English! When
the English land owners enjoyed the beautifully barbecue prepared by
the gauchos (cattle station workers), they said "give me the curry"
("givmidecurri") which ended up been Chimichurri.    

The Argentinean legend Willy Polvoron:

"La vida es una susecion de Asados", in english "Life is a succession of BBQs".

The maximum expression of the Cumbia Parrillera!
