Farming abalone has become common in areas where this special animal lives. It ensures sustainably raised abalone if you buy it from a reputable supplier. Because they grow so slowly, farmed abalone is much smaller than those gathered in the wild. Remember that finding a deal on this or any other seafood can mean that it is inferior in quality or illegally harvested. Fresh abalone can often be shipped overnight.
As with all seafood, when buying it fresh make sure it has no off smells. Abalone should be cleaned and cooked the same day for best results. Canned, cleaned, and cooked abalone, as well as dried abalone, can be found in well-stocked markets. Though convenient, it is expensive.
