Grouper is a mild white fish, with flakes that are large and flaky. It can be used in any recipe where you would typically use cod or haddock. However, it’s also delicious all on its own! If you’re looking for something new to try, Grouper Reuben Sandwiches are a must-try.
Grouper is available year-round, but it’s best known as a wintertime fish. Back in the day, before refrigeration was common, grouper was so plentiful during the colder months that fisherman would put them in ice to keep them fresh until they returned to port. Since then, the name stuck and grouper has been a popular dinner fish.
