Aunt Corrine’s Crab Gumbo & The Toothbrush Rule

Everybody in Manchac knew 3 things: Aunt Corrine made the best gumbo, she cussed at the Saints, and she cleaned her crabs with a toothbrush. Here’s the recipe and the reason.

My Aunt Corrine didn’t play about seafood. If you brought her crabs from the river with mud still in the joints, she’d send you back to the bayou. If you tried to throw a whole crab in her gumbo pot without scrubbing it first, she’d smack you with a wooden spoon and say, “You trying to feed my family the ditch?

So every crab got a bath. With hot water and a toothbrush. Here’s why, and here’s her recipe.

 

Why Aunt Corrine Cleaned Crabs With a Toothbrush

Blue crabs live in mud. They walk through it, eat in it, and drag it into every crack of their shell. If you boil a dirty crab, all that mud goes into your gumbo stock.

Muddy crab = muddy gumbo. Clean crab = sweet gumbo.

Aunt Corrine kept a whole cup of old toothbrushes by the sink. Not for teeth. For crabs.

She’dRinse crabs in cold water to wake them up. Yes, alive. That’s how you know they’re freshFlip them over and scrub every leg joint, the apron, and under the shell flap with a stiff toothbrushPull the top shell off, take out the “dead man’s fingers” and the guts, rinse againOnly then did they go in the pot.

It takes 10 minutes longer. It makes your gumbo taste like the Gulf instead of the ditch. That’s the Toothbrush Rule.

 

Nana's Crab Cleaning Rules From Aunt Corrine

1. Buy live crabsIf they don’t move, don’t buy them. Dead crab spoils fast.

2. Ice them first20 minutes in a cooler of ice puts them to sleep. No pinched fingers.

3. Never boil a whole crab with gutsIt makes the stock bitter. Clean them first

4. Keep a “crab toothbrush.” Mark it with red tape. Pawpaw used it on his teeth once. Once.

Instructions

Clean the crabsSee Toothbrush Rule above. Save the top shells to make stock if you have time. Break bodies in half.

Make a dark rouxFlour + oil in a heavy pot. Stir non-stop on medium 25-30 minutes until it’s the color of Aunt Corrine’s kitchen table. Chocolate brown. Don’t burn it.

Add trinity Onions, bell pepper, celery. It will sizzle and stop the roux from cooking. Stir 5 minutes until soft. Add garlic. Stir 1 minute.

Build the gumbo Slowly pour in 3 quarts hot stock while stirring. Add bay leaves, Tony’s, thyme, cayenne. Bring to a boil, then simmer 45 minutesAdd okra + crabsSimmer 20 minutes. The crab shells flavor the pot.

FinishAdd shrimp + crabmeat. Cook 5 minutes until shrimp are pink. Turn heat OFF. Wait 5 minutes.

ServeLadle over rice. Pass the file. Each person adds ¼ to ½ tsp to their own bowl.  Never boil fileYou’ll know it’s right when the broth is dark, the crab is sweet, and there’s no grit between your teeth. That’s Aunt Corrine’s standard.
