Just called my favorite Seafood Market. They have crayfish tails in stock. Frozen, but beggars can't be too picky.
In a couple of hours I'll run by and get my Little Bit for the weekend. We'll hit the market, the produce stand for the trinity (onion, bell pepper and celery) then its home to quick thaw some shrimp stock. Before long the house should smell awful good. Wish you could join us.
I give you Deep South Dish's Crawfish (or Crayfish, depending on where you're located) Etouffee.
Have a great weekend.
