  A Gulf Coast tradition, originally from Bayley's Restaurant near Mobile, Alabama.​  Mr. Bayley invented this salad. This is my take on it!

Ingredients
1 pound fresh lump crabmeat, picked over for stray shells
1 medium onion, chopped fine
4 ounces extra-virgin olive oil
3 ounces apple cider vinegar or rice wine vinegar
4 ounces ice water
salt and pepper to taste
lemon wedges, lettuce, saltine crackers, green onion tops for serving
Steps
  1. ​Spread half of the chopped onion over the bottom of a large mixing bowl.  Place crabmeat on top of this.
  2. Spread the rest of the onion on top of the crabmeat.
  3. Salt and pepper to taste.
  4. Pour over all of this in order:  oil, then vinegar, then ice water.
  5. Cover and place in refrigerator to marinate from 12 - 24 hours.  The longer it marinates, the better it is!
  6. When ready to serve, toss lightly, but don't stir.
