Live Whole Red Sea Urchin (Short Spined) 2 UrchinsThe south coast of Australia is home to the red sea urchin, which is found there. Its colour ranges from red to burgundy. Sea urchins have an umami salty sweetness because they are rich in sugar, salt, and amino acids. They often taste like the seaweed they eat, much like oysters. However, all good urchins should have a buttery, melt in your mouth texture and a rich, distinctive flavour that has been compared to eggs, lobster, foie gras, and fish roe.
