Imitation crab is not fake crab and it is not inferior to real crab

Imitation crab is not a cheap alternative to real crab. It is a different ingredient with its own Japanese culinary tradition, its own preparation technique, and its own flavor profile that works specifically well in sushi.
The ingredient has a mild umami flavor distinct from fresh crab. It is called surimi, a Japanese word meaning ground fish. It is classified as a processed seafood product. It is made from pollock or other white fish that is deboned, minced, formed into sticks, and flavored to mimic the mild sweetness of crab. The technique was developed in Japan in the 1970s as a way to use fish that would otherwise go to waste. It arrived in the US in the early 1980s and became the primary filling in California rolls almost immediately.
Real crab in sushi exists and is excellent. But imitation crab is not a substitute for it. It is a different ingredient for a different dish. A California roll with real crab, wrapped in nori seaweed, served with pickled ginger and soy sauce, would be a different dish in Japanese cuisine altogether.
What is imitation crab made of?
Surimi is made from minced pollock fish combined with starch, egg white, sugar, salt, and crab flavoring. Fully cooked during manufacture.
The nutritional profile makes it a reasonable seafood option. Lower in fat than real crab, moderate in protein, and lower in cholesterol. It contains real fish, unlike some imitation seafood products.
The ingredient is sold in most supermarkets near the seafood counter in the refrigerated section. Unlike the commercial bulk products on Amazon (designed for restaurant use), the supermarket version in 8 to 12 oz packs costs $3 to $6 and is the right size for home sushi. Standard brands like Louis Kemp Crab Delights and Trans-Ocean Crab Classic are widely available. Both use a stick format that shreds easily. The flake format is less useful for sushi because the irregular pieces do not layer as well in rolls.
How do you prepare imitation crab for sushi?
Pull sticks apart lengthwise with your fingers to shred. Do not cut. Rough strands hold together in a roll better than clean-cut pieces.
Take one or two sticks and slice or pull them apart lengthwise. The crab should separate into rough strands. Use chopsticks to arrange the strands or to pick them up when serving. For tempura variations, coat a whole stick in tempura batter and fry before adding to a roll. Lay 3 to 4 strands in a line across the rice in your maki roll. This is the standard filling technique for California rolls.
For a spicy crab mix, combine shredded imitation crab with Japanese mayo (Kewpie brand) and sriracha. Mix until the strands are coated. This is one of the most popular roll fillings and the basis for most "spicy crab" maki rolls at sushi restaurants. For a garnish, a few pieces of tobiko roe scattered on top add color and texture to a finished sashimi platter or nigiri plate. The dipping sauce flavor comes through better when the mix is slightly chilled.
What does imitation crab taste with sushi?
A mild, slightly sweet seafood flavor that does not compete with soy sauce and wasabi. The texture is soft with a slight springiness.
The serve temperature affects flavor. Cold imitation crab from the fridge has more defined flavor. Room temperature imitation crab is softer and less distinct. For the best results in a California roll, use it straight from the fridge.
Nigiri with imitation crab on top is less common than nigiri with fish but works well for non-raw options.

For the rolling technique, read how to roll uramaki.
