Black Clam Ceviche (Mexican Style)

This ceviche is the 'dark horse' of seafood—literally. 'Conchas negras' (black clams or blood clams) are famed for their dark liquor and intense, briny, iron-rich flavor. Not a starter dish, but a gourmet adventure. The dark clam juice mixes with lime and veggies for a dramatic looking, deep-tasting dish revered in Latin America as an aphrodisiac.

Instructions

1

Scrub clams under running water. Open with a knife, collecting all the dark juice in a bowl, and scrape out the meat.

Tip: The juice is the soul of this dish—do not discard!
2

Chop meat into bite-sized pieces and return to the juice. Add lime juice and let sit in cool place for 10-15 minutes.

Tip: Don't over-marinate or they turn rubbery.
3

Slice onion very thinly; dice tomatoes; mince chili and garlic.

Tip: Thin onions add crunch without overpowering the clam.
4

Mix veggies and cilantro into the clam mixture. Season with salt and pepper.

Tip: Taste first; clams are naturally salty.
5

Right before serving, cube avocado and fold in gently.

Tip: Avocado fat softens the sharp acid and spice.
6

Serve cold, juice and all, with saltines or corn chips.
