Crab Showdown: The Firm Texture of King Crab vs. The Delicate Sweetness of Snow Crab

To me, the king crab, which is the favorite of Taiwanese people, is like a king, while the snow crab is like a queen. Look at these tension-filled crab legs, shining with a moist luster under the light. The king crab emphasizes the "thickness of the meat." The crab meat, after being boiled, has a fresh and sweet chewiness, and each bite is a heavy hit from the sea, suitable for hardcore diners who enjoy the pleasure of "eating meat in large bites." The texture is relatively firm and chewy.

A little trivia: Is the king crab actually not a "crab"? This might be the biggest piece of trivia: in biological classification, the king crab actually belongs to the "superfamily Lithodidae," and in terms of genetic relationship, it is closer to "hermit crabs" than to regular crabs. The simplest way to identify them is by counting their legs—true crabs have ten legs, but the king crab appears to have only eight legs (the other two are atrophied and hidden under the shell), which is also one of the reasons they can grow so large while having such elastic meat.

Snow crab is a species of crab native to the Sea of Japan and the northwest Atlantic Ocean, and it is known by various names in Japan, such as "Taiza crab," "Shibayama crab," and "Maizuru crab." It, along with king crab, is one of the two most important ingredients in crab cuisine, and snow crab is particularly a high-end dish available only in winter. Compared to the firm meat of king crab, snow crab has a more delicate and sweet flavor, with a tender texture that is suitable not only for sashimi but also as an ingredient for shabu-shabu.

In addition, the crab roe of snow crab is also very rich, providing another unique flavor in addition to the delicious crab meat, making it suitable for making rice porridge or stews. Don't miss the next dish!

One of the popular dishes here, a traditional Japanese dish - crab miso baked in the shell.

After finishing the crab legs, you must try this dish! "Kora" in Japanese refers to the crab shell, and "Kora-yaki" is a grilled dish that uses the crab shell as a container for direct grilling. The method involves placing crab roe into the crab shell, then adding sake, mirin, and chopped green onions. Here, we use "Kani Miso Kora-yaki," where the crab shell filled with ingredients is placed on a baking tray and heated over a flame. As the ingredients gradually boil, watching the crab roe slowly bubble up over the fire, the rich aroma of chitin activated by the charcoal is definitely a temptation for the sense of smell! The fragrance of the crab roe becomes concentrated due to the high temperature, and the smell rich in chitin not only whets the appetite but is also an excellent choice for a side dish with drinks. After enjoying the steaming hot crab roe, don’t be in a hurry to throw away the crab shell!
I recommend trying the authentic Japanese way of eating, leaving a little leftover ingredient, and pouring sake into the crab shell to drink it together with the remaining crab roe, which becomes the classic "Kora-zake." I also recommend it as a dipping sauce for crab legs; I personally highly recommend this way of eating.

Treasure Box at the Bottom of the Sea - Wooden Box of Sea Urchin Sushi

The rich sea urchin piled on top, glistening salmon roe overflowing. This meticulously designed dish immediately catches the eye. It is not just a delicacy, but a visual feast prepared by the crab with great care for its esteemed guests who have come from afar. A wooden box filled with crab meat, sea urchin, and vinegared rice. Unlike a simple container, this square wooden box is called "枡" (pronounced: masu). In fact, it was originally not a vessel for alcohol, but an ancient Japanese measuring tool used for rice, beans, or sake. Later, because the pronunciation of "枡" (Masu) is the same as the Japanese words for "increase" and "gain," it was considered very auspicious and evolved into a container used during celebrations or to entertain esteemed guests.

When we drink sake in a restaurant, the staff usually fills the cup to overflowing, and the masu is also filled to the brim. Not only is it a visual delight, but it also has a story. This pouring method has a beautiful name called "盛っ切り" (Mokkiri). The intention of the establishment is very straightforward: "The hospitality is overflowing." This is a way to show enthusiasm, generosity, and sincerity, representing that the establishment is not stingy and wants to pour the best and fill it to the top for the guests.
