Today's challenge was KASTERA.

KASTERA rich but soft golden sponge cake made of egg, sugar, white strong flour.

This japanese cake originated in Portugal.
Portugal is one of the first countries that reached the east Japan.
So for us, every thing they brought, introduced were quite interesting.
(But after this Japan had a special intended isorated period.)

The texture is very tender.
Nice with not only Japanese green tea but Chinese tea, English tea, coffee.

I ate a little today and wait until tomorrow for more tender rich taste!
