@panzade,
Good day panzade.
Many variations of chimichurri I have tasted. Here are two.
Traditional from Argentinian friend.
Sixty percent corn oil to forty percent white vinegar. For every one cup of liquid, add half cup of chopped parsley, one eighth cup chopped hot red pepper flakes, and half of a medium sized bulb of garlic. Put in container/jar, and stir with spoon. Needs a minimum of twenty four hours to become a happy family.
My way. Sixty percent Filippo Berio olive oil. Forty percent white vinegar. Same quantities as parsley, crushed red pepper, and garlic. Blend. Instant buffalo breath (nephews term)
I like "churri"( slang) on breaded items, especially, bone in pork chops, or steak siciliano.
