Castella prep times 10–11am at a Gimpo Gurae-dong bakery: Jinsim
Jinsim Castella Gimpo Gurae Main Branch is a castella specialty shop on Gimpohangang 4-ro in Gurae-dong, Gimpo, Gyeonggi. Two boxes for the kids — original whipped cream castella and chocolate whipped cream castella at 9,700 won each — came to 19,400 won, and the two flavors tasted clearly different. Jinsim Castella bakes its castella in stages between 10 and 11am, so check the timing if you want a specific flavor.
