The orange-and-white stick in your California roll has never been near a crab. It is Alaska pollock, washed and deodorised into a blank protein paste, coloured with paprika, flavoured in a laboratory, and then cut by a row of blades so your teeth read crab fibres.
This is the story of a nine-hundred-year-old Japanese preservation trick that became the cheapest, most convincing piece of seafood in the world, and of what the science says about the difference between tasting something and believing it.
You'll find out:
- What is actually inside a crab stick, ingredient by ingredient
- How fishermen in Heian-era Japan invented surimi to keep fish edible
- The nineteen sixty-nine discovery that let surimi be frozen and shipped
- The patent race that produced the stick shape in the nineteen seventies
- The blade-scoring trick that makes a gel sheet tear like crab
- Why blind tests say your tongue is not the one being fooled
