literally means "vegetarian fin". A Taiwanese manufacturer's recipe for it contains water, gelatin, alginic acid, sugar, casein, and triolein to reproduce the chewy, gelatinous texture of shark fins. However, some of these imitations absorb the broth more quickly than the real shark fin. Konjac gel (known as moyu tofu in Chinese Mandarin, mo wu dau fu in Chinese Cantonese, and konnyaku in Japanese) can also be used as a substitute for shark fin once it is julienned into thin strands using a chef's knife, produce slicer, or food processor. While cellophane noodles are also often used as an alternative to shark fins, some cooks find them too soft and unable to withstand simmering long enough for flavors to be absorbed, consequently the imitation shark fin or julienned konjac gel are more desirable. Other substitutes include Cucurbita ficifolia (shark fin melon, shark fin soup squash), chicken breast, jinhua ham, vermicelli, soy, sea cucumber, bird's nest, pig's skin and gelatin. In 2015, a seafood company from San Francisco was working on a variation of imitation shark fin using algae-derived ingredients and recombinant proteins. Alternatives to shark fin are inexpensive and easier to prepare. Imitation shark fin, konjac gel, and other alternatives can be purchased in preserved form from Asian supermarkets and convenience stores.

The mixture, which was cooked into a soup, was served in a small bowl. Although this soup was inexpensive and lacked the authentic flavor, since it was cheap, tasty and contained many ingredients, it was popular among the poor and became one of the famous street snacks of Hong Kong. Apart from the street vendor version, imitation shark fin soup may also be found in fast-food stores and expensive Chinese restaurants in Hong Kong, and also on mainland China. Since April 2016, Cup Noodles released various instant imitation shark fin ramen soups. Controversy False descriptions of goods and services are prohibited by the Trade Descriptions Ordinance in Hong Kong. Thus, imitation shark fin soup may have to change its Cantonese name since "wun tsai chi" (literally: "fin in little bowl") may
