Grilled calçots / calcots, a special type of large spring onion grown in Catalonia that I didn't think I'd get to try because it was out of season. (In fact, the reason I picked this restaurant when walking down the street and reading menus was because it was on the menu.)
The staff had to teach me how to eat them. First, they gave me gloves because the calçots were too hot to touch. Then they provided a bib. To eat the calçots, I had to grab the root and yank (like removing a sleeve), thus peeling off the charred outer layer. Once I had the white insides, I dipped them in the accompanying romesco sauce and ate them. The gloves were important--even if I could peel them, the insides were too hot to lift to my mouth without gloves.
These grilled calçots tasted like soft, grilled green onions (naturally) with a "grain" in one direction (a la how meat has a grain). The plate was too big for me; this many onions got to me.
