Recipe: Kastera or Castella Cake (Japanese)

Here's a Kasutera recipe I worked out over many tries some years back. There's also one in "At Home with Japanese Cooking" by Elizabeth Andoh.

6 eggs
3/4 cup sugar
1/3 cup honey
1 cup flour, sifted
1 teaspoon baking powder
confectioners' sugar

Preheat oven to 350.

Using an electric mixer, beat 3 eggs and 3 egg yolks unitl light. gradually adding sugar, beat until mixtuer falls in ribbons, about 6 minutes. Beat in honey, pouring it in a thin stream.

Sift together flour and baking powder. Fold into egg mixture.
Beat remaining egg whites until stiff. Fold into egg mixture.
Bake 45 minutes in a well-greased 9" square cake pan. Check cake after 30 minutes and if the top is golden, cover with foil and continue baking.

Remove from pan. Reinvert and let cool on a wire rack.
Sprinkle top with confectioners' sugar.

P.S. This is not in Hawaiian cookbooks, although Japanese stores in Hawaii sell it! (I live in Hawaii.)
