I've had artichoke in stuff. But never actually a whole thing like that. Wouldn't even know what to do with it. Or even what it tastes like on it's own. LOL
Pull off the leaves and dip the bottom end in hollandaise sauce and "scrape' it off with your teeth...
Then take the heart (bottom part) and pull the thinner/smaller leaves off scrape the furry part off of it and eat that with the hollandaise sauce... The hearts are the best...
