Sea urchin ceviche is a delightful seafood dish that combines the delicate flavors of fresh sea urchin with a tangy marinade. This recipe showcases the natural sweetness and brininess of sea urchin, creating a unique and refreshing culinary experience. In this article, we will explore the step-by-step process of preparing sea urchin ceviche, along with tips, variations, and frequently asked questions.

What is Sea Urchin Ceviche?

Sea urchin ceviche is a dish that originated in coastal regions where fresh seafood is abundant. Ceviche itself is a traditional Latin American dish that typically consists of raw fish or seafood marinated in citrus juice, such as lemon or lime. The acidity in the marinade helps “cook” the seafood by denaturing the proteins, resulting in a slightly firm texture and a bright, tangy flavor.

Sea urchin ceviche takes this concept and elevates it by using the rich and creamy roe (eggs) of the sea urchin as the star ingredient. The roe, often referred to as uni, has a distinct taste that is both sweet and savory, with a hint of the ocean. When combined with the citrus marinade, it creates a harmonious balance of flavors.

Health Benefits of Sea Urchin

Sea urchins are not only delicious but also offer several health benefits. They are an excellent source of omega-3 fatty acids, which are essential for brain health and reducing inflammation in the body. Sea urchins are also rich in vitamins and minerals, including vitamin B12, vitamin C, zinc, and iron. These nutrients contribute to a healthy immune system, improved blood circulation, and optimal cellular function.

  • Cilantro (a handful)
  • Salt (to taste)
