Today, I’ll share a sweet recipe that transported from halfway across the world to our family kitchen in the Midwest: the delightful Castella cake. Originating from Portugal, this sponge cake found its way to Japan in the 16th century and became a beloved treat. Making Castella is like weaving a bit of history into each bite, and its simple elegance makes it perfect for any gathering or a quiet afternoon tea.
Castella cake is wonderfully versatile when it comes to pairing with other treats. For a traditional touch, serve it with a cup of hot green tea or your favorite coffee. To make it a bit more indulgent, a dollop of whipped cream or a scoop of vanilla ice cream goes beautifully. And for those cozy gatherings, a side of seasonal fruit compote makes the cake even more special.

6 large eggs
150g or 3/4 cup bread flour, sifted
2 tablespoons honey mixed with 2 tablespoons warm water

Variations & Tips
For a little twist on the traditional recipe, you can add a hint of citrus zest (like lemon or orange) to the batter for a fresh, zesty flavor. Another popular variation in Japan is to include matcha powder, giving the cake a distinctive green tea flavor that’s both sophisticated and refreshing.
