Abalone is a large marine gastropod mollusk (that's a sea snail to you and me) with extremely rich, flavorful meat that is highly prized. So highly prized, in fact, that they were brought to the brink of extinction on the West Coast. Careful management has brought population levels back a bit and some recreational harvesting is allowed. For those of us not brave enough or geographically situated to dive for abalone, farmed abalone is increasingly available.

It needs tenderizing (or long, slow cooking to tenderize it) or it has the texture of a dried-out tire. These recipes are a great way to enjoy the rare, wonderful treat that is fresh abalone:
Where to Get Abalone

For the rest of us there are several abalone farms in California and Hawaii. The
Monterey Abalone Company has been growing abalone under the piers in downtown Monterey since 1996 and sells sustainably raised red abalone live, shipped overnight.

The abalone attaches to its shell with a solid round muscle at the bottom, everything else is just clinging to the shell. Open a section between the abalone and the shell by working the spatula between the non-attached flesh and the shell until you hit the muscle that is attached to the shell. Then work the spatula around and along the between the muscle and the shell until the abalone detaches. Push against the shell with the tool rather than the abalone for easiest release and to keep the abalone whole.

How to Tenderize Abalone

Photo © Molly WatsonThere are a couple ways to tenderize the potentially tough flesh of succulent abalone. The first, and most common way, is to gently but thoroughly pound each slice of abalone with a meat tenderizer or the back of a large spoon.
A second option is to pound the entire cleaned abalone - this can be done by wrapping the cleaned abalone in a clean towel and pounding it with a baseball bat or similar piece of wood, being careful to pound gently to avoid tearing too much of the abalone flesh.
A final way to tenderize abalone is in the cooking, by braising or stewing it.
