I am very confused here.
Just typed in California Roll in Google.
In the 1960s, Los Angeles, California became the entry point for sushi chefs from Japan seeking to make their fortune in the United States. The Tokyo Kaikan restaurant then featured one of the first sushi bars in Los Angeles. Ichiro Mashita, a sushi chef at the Kaikan, began substituting avocado for toro (fatty tuna), and after further experimentation, the California roll was born.
But Tojo website also says
For those who felt uneasy about eating raw fish, there was cooked crabmeat
and avacodo, rolled “inside out” to hide the seaweed wrapper (another challenge for many). Thus was born what is now universally known as the “California roll”—not for its land of origin, but for the avocado. Today this is the staple sushi for millions of North Americans who have no idea that it originated with Tojo, in Canada. http://www.tojos.com/tojomenu.pdf
So........Was california roll Really originally invented by Tojo ????
