Use 2 pounds of any seafood you like. If using imitation crab, cut it into small bite-sized pieces and cook in butter until it softens up a bit and starts to brown slightly on one side. It will taste much better this way.
For a stronger flavor in the rice, use 2/3 cup vinegar and 1/3 cup sugar.
Consuming raw seafood may increase your risk of foodborne illness, especially if you have certain medical conditions.
