If you’re a fan of Japanese, Korean, or Chinese cuisine, you may have heard of kani butter. Kani is the Japanese word for crab, so kani butter is also known as crab butter (not to be confused with actual butter you may dip your crab meat into for western style cuisines).
For some people, kani butter is the best part of the crab. For others, the idea of consuming crab juices from its innards takes a bit of time to get used to. Let’s dive in!
What is Kani Butter?
Kani Butter, or crab butter, is the rich, creamy greenish-yellow or brown liquid inside a crab when you crack it open. There’s a bit of confusion on the internet on what to call it, but kani butter is also known as, crab tomalley, crab mustard, or crab fat. It is celebrated for its unique flavor, which adds a delightful dimension to the crab-eating experience.
Where does Kani Butter come from?
Kani butter comes from the central part of a crab’s body cavity. It is a gland, specifically the hepatopancreas, which serves a multi-functional role in the crab’s digestive system. The hepatopancreas produces digestive enzymes that break down food and filter impurities from the crab’s blood, similar to the functions of the human liver and pancreas. The substance is soft and creamy in texture, with a greenish-yellow or brown color.
What does Kani Butter Taste Like?
Kani butter is a unique ingredient that can add a natural umami flavor to your dishes. The taste of kani butter is sweet and slightly musky or nutty with a hint of brininess. Some people consider kani butter to be the most flavorful part of the crab.
Why do people eat crab innards?
People eat crab innards, such as kani butter (crab tomalley) and other internal organs, for several reasons:
Flavor: Crab innards, like kani butter, have a unique and distinct flavor that some people find highly appealing. The slightly nutty and briny taste adds a rich and savory element to dishes, enhancing the overall flavor.
Texture: The creamy texture of crab innards, similar to butter, can provide a luxurious and smooth mouthfeel when incorporated into dishes. This texture can be particularly enjoyable for those who appreciate a contrast to the firmness of crab meat.
Minimizing Food Waste: Many culinary traditions and cultures have a strong emphasis on minimizing food waste. The Japanese even have a word for this – mottainai. Eating crab innards is a way to make use of every part of the crab, reducing waste and making the most of the animal’s resources.
Culinary Versatility: Crab innards can be used in a variety of ways in cooking, adding depth of flavor and richness to dishes. They can be used as a topping for sushi, mixed into crab dishes, or even enjoyed on their own in different preparations.
Cultural and Regional Traditions: In some cultures, particularly in Asian cuisine, the consumption of crab innards is a longstanding tradition. These innards are considered a delicacy and are enjoyed in various culinary preparations.
While many people enjoy crab innards, others may not find them to their taste. Culinary preferences vary widely, and what is considered a delicacy in one culture may not be as popular in another.

Where Can I Try Kani Butter?
