This infographic titled "Sushi chemistry: nori, wasabi and sticky rice" explores the science behind sushi. It features three main panels with illustrations, chemical structures, and explanations. The left section explains how amylopectin in rice creates stickiness and how acetic acid from vinegar aids gelatinisation. The middle panel covers umami flavours from glutamate, inosinate, and guanylate found in nori and raw fish, displaying their molecular structures. The right panel discusses allyl isothiocyanate in wasabi and horseradish, along with gingerol and shogaol compounds in pickled ginger (gari). Photos of six different sushi rolls line the bottom.

Did you know that the wasabi in most supermarkets and restaurants isn’t wasabi? Or that a chemical synergy between dried seaweed and raw fish enhances the savoury flavour of sushi? This infographic was a request from my sushi-mad seven-year-old son and looks at a range of sushi science, from the sticky rice to the pungent pickled ginger.
