Bijuu Co., Ltd., the manufacturer and seller of Kyoto specialties like 'Tsubuan-iri Nama Yatsuhashi Otabe' and 'Kyo Baum,' will launch a limited-time summer product, the 'Miyuka Nama Butter to Lemon An no Fuwa-Shari Sand,' on Friday, May 22, 2026. The product will be offered through its Tokyo-based brand, MIYUKA.
The development of this sandwich began with the discovery of the surprisingly good compatibility between lemon and 'an' (sweet bean paste), resulting in a product designed for the summer season.
■ A Layered Flavor Profile
The sandwich consists of a white bean-based 'lemon an' and an Earl Grey-infused 'tea butter,' layered between soft langue de chat cookies. The lemon an contains pulp for an added textural element. The aroma of tea is fat-soluble and is designed to emerge after the initial refreshing scent of lemon. To achieve this effect, the ingredients are kept in two separate layers instead of being mixed, allowing the acidity of the lemon to be gently supported by the fragrance of the tea.
■ Balancing Sweetness and Acidity
A key focus during development was controlling the acidity of the lemon. The company conducted numerous trials, using a paste made from lemon peel and pulp, to find the perfect balance that would not overpower the elegant sweetness of the bean paste or the richness of the butter. Earl Grey was chosen for the tea butter due to its compatibility with lemon, creating a refreshing flavor suitable for summer. The company also suggests pairing the sweet with hot tea.

■ The Secret to the 'Fuwa-Shari' Texture
The 'Miyuka' series is characterized by its 'fuwa-shari' (fluffy and crisp) texture. This is achieved through a calculated moisture content in the bean paste. Over time, this moisture migrates to the langue de chat cookie, causing it to evolve into a 'fluffier' texture. The design ensures the sweet is enjoyable both immediately after purchase and later on.
