Datemaki Day (Datemaki no Hi)

What Is Datemaki Day?

May 24th is "Datemaki Day." This anniversary was established by Sennichi Sohonsha Co., Ltd. (now Sennichi Co., Ltd.), a company in Suita, Osaka, that makes tamagoyaki, thick omelets and other sushi toppings. The date marks the death anniversary of the samurai lord Date Masamune (May 24 in the old lunar calendar), who is sometimes linked to the origin of the name "datemaki." The day aims to pass on datemaki (a sweet rolled omelet), a staple of osechi (Japanese New Year) cuisine, as part of Japan's food culture.

The History and Cultural Background of Datemaki

Datemaki is a traditional Japanese egg dish known for its sweet flavor and fluffy texture. It is a beloved staple of osechi, the special dishes eaten during the New Year.

• An egg dish made with fish paste: Datemaki is made by blending white fish or shrimp paste with egg and dashi, seasoning it with mirin and sugar, baking it, and rolling it with a bamboo mat while still hot.
• The origin of the name "date": Because its shape and color are more elaborate than an ordinary omelet, it is said to be named after "date-mono," a word for something stylish or showy. Another theory links the name to Date Masamune, who is said to have liked the dish.
• Its role in osechi: Because its rolled shape resembles a scroll, datemaki is considered a lucky food associated with gaining knowledge and academic success.

The Science Behind Datemaki's Texture and Flavor

The fluffy texture of datemaki comes from the unique structure created when egg and fish paste are combined.

• Springiness from fish paste: The proteins in fish paste coagulate when heated, creating the dish's characteristic springy texture.
• Air bubbles in the egg: Thoroughly whisking the eggs incorporates air, resulting in a fluffy finish once cooked.
• Why it's rolled with a bamboo mat: Rolling the dish with a bamboo mat creates datemaki's signature spiral pattern, emphasizing its beautiful appearance.

Interesting Facts About Datemaki

• Also in Osaka-style sushi: Besides osechi, datemaki is used as an ingredient in Osaka-style sushi.
• Variations in ingredients: Traditional datemaki is made with white fish paste, but many home recipes today use hanpen (a type of fish cake) instead.
• Good for storage: The generous use of sugar helps preserve datemaki, making it well suited for osechi, which is prepared in advance.
• The meaning of the spiral pattern: The scroll-like shape evokes "knowledge," "culture," and "learning," adding to its value as a symbol of good fortune.
