Authentic Taiwanese Castella in Ueno: Traditional Recipe, Premium Japanese Ingredients and a "Fuwa-Shuwa" Texture Worth Queuing For

[Ueno] Taiwanese Castella Specialty Shop Opens in Ueno! Its "Fuwa-Shuwa" Texture, Made with an Authentic Taiwanese Recipe, Is Getting Attention
Overview
A new shop selling Taiwanese castella is opening in the Ueno area. Taiwanese castella is a sponge cake made with lots of eggs and baked in hot, humid steam. This gives it a unique texture that is fluffy and melts in your mouth. The number of specialty shops in Japan has grown in recent years, and the cake has become very popular.
The new Ueno shop reportedly follows the traditional Taiwanese recipe faithfully but uses premium Japanese ingredients. The shop says its "fuwa-shuwa" (fluffy and melt-in-your-mouth) texture comes from combining traditional Taiwanese baking methods with a Japanese focus on quality ingredients. Taiwanese castella's texture changes as it cools after baking, so many shops draw lines of customers who want it fresh from the oven. The new shop is also expected to become a popular spot where queues are a given.
The title of the announcement was cut off partway, so details such as the shop's name, location and opening date are not yet known. We will share updates as more information becomes available.
