No, the ingredients I listed are _COMMONLY_, even _USUALLY_, in
California rolls.
Your attempting to say that these ingredients "can" be in Califonria
rolls is just disingenuous. See any number of entries, histories,
variations, etc. A couple:
""California rolls, consisting of avocado, imitation crabmeat, and
mayonnaise encased in rice with sesame seeds on the outside, are an
excellent example of Japanese American food. The rolls were invented by
Japanese chefs in Los Angeles during the 1970s for Americans who were
squeamish about eating raw fish. California rolls became a popular
addition to Japanese restaurant menus in the United States during the
1980s, and there were eventually exported back to Japan, although many
sushi purists eschew them, as they were not a traditional Japanese
food." ---Oxford Encyclopedia of Food and Drink in America, Andrew F.
Smith editor [Oxfod University Press:New York] 2004, Volume 1 (p. 728)"
"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.[2] (The date is often
given as the early 1970s in other sources.)[3][4][5] Mashita realized
the oily texture of avocado was a perfect substitute for toro.[3]
Traditionally sushi rolls are wrapped with nori on the outside. But
Mashita also eventually made the roll "inside-out", i.e. uramaki,
because Americans did not like seeing and chewing the nori on the
outside of the roll.[3]" (Wikipedia)
And so on. Avocado clearly plays a central role in making the
California roll what it was. After all, avocados were not common in
Japan, and aren't today unless imported for, drum roll, the California
roll.
