Italian or curly.
To me, it has the flavor of grass (or some nondescript plant matter). Bitter grass.
Used as a main ingredient (as in tabbouleh - I don't like tabbouleh) or as an herb (just about everything else), I don't care for it.
It looks pretty on a plate but that's about it. When I eat something that's been sprinkled with parsley, I try to pick them off because it tastes grassy and throws off the other flavors of the dish.
Does anyone else feel this way about parsley? It is so ubiquitous in restaurants and recipes alike. Why is parsley so popular? I just don't get it.
