A California roll recipe is usually made with imitation crab meat, cucumber, and avocado. Yes, that is not usually "real" crab meat in your California roll.
You might want to consider using real crab such as Alaskan King crab meat. This crab is considered a delicacy because men have to literally risk their lives to catch these crabs.
Imitation crab meat is actually made from fish and is a pretty processed food with all kinds of questionable ingredients.
The California roll was created in California by an authentic Japanese sushi maker and you will find it at most Japanese restaurants in America.
Alaskan King crab meat ironically comes from the same sea as the imitation crab meat fish. The icy waters of the Bering Sea produces one of the best tasting crab meat - The Alaskan King crab.
Alaskan King crab meat is known for its sweet tender texture and this crab is also known for its very large size. It is a special treat to get your hands on this type of crab meat and you will probably not be able to buy it fresh unless you live in Alaska.
Imitation crab meat is usually made from Alaska Pollock which is a fish found in the Bering Sea which is near Alaska.
Pollock isn't the only fish used to make imitation crab meat, but it is the most common fish used because it has a very mild flavor.
This fish has to go through a lot of processing to create a thick paste or crab like appearance.
There are many other ingredients that tend to be added such as sugar, wheat, vegetable oils, natural & artificial flavors, and food coloring to make this fish resemble crab meat.
And among the ingredients used to make this "crab" meat, you will usually not find one trace of crab. Although, it will actually pass as a Kosher food because it is not made from shellfish.
Peel the cucumber and cut the cucumber in half.
Slice into the cucumber and carefully move your knife along the outer part - to create a thin layer of cucumber.
Then cut the thin layer of cucumber into the appropriate length (6 to 8 inches).
Next, place your sushi ingredients (horizontally) to fill the middle of cucumber wrap.
Then fold one cucumber end over your sushi ingredients and tuck in before starting to roll.
Basically, you tuck and roll until you reach the other end of the cucumber wrap.
You can use toothpicks to keep the wrap intact and slice your rice-less sushi roll.
I've actually ordered this type of sushi from a sushi place and it's pretty tasty.
If you are on a low carb diet or on a grain free diet (paleo, ketogenic), this is the perfect sushi alternative for you - using a cucumber to wrap your sushi ingredients!
You can turn this into a California roll by using real crab meat, avocado, and the other ingredients that go into a California roll (except the rice).
