Chimichurri's etymology is steeped in lore, with some claiming it originated with an Irishman named "Jimmy McCurry" or a British meat man named "Jimmy Curry," while others say it's a mangled version of the phrase "give me the curry." All we know for sure is that this tangy Argentinian sauce is a revelation with flank steak, complementing its hearty flavor with the herbal notes of fresh parsley and olive oil.
