Hi everyone,

After eating my first curry donut, from a Japanese bakery, I'm
determined to figure or find out how to make this amazing but
improbable sounding food.

The exterior appears to be a standard yeast-raised donut, but coated
in panko. The curry filling (at least in the one I had) appears to be
a Japanese style curry with conspicuous bits of onion and carrot in a
thick spicy gravy. The exterior of the donut offered little clue as to
when or how the curry center was formed (ie, introduced before or
after frying, and how - though I didn't see a hole when I looked).

Does anyone have any more in-depth information?

Also, if anyone can recommend a Japanese cookbook for baked goods
(breads and perhaps donuts as well) I'd be grateful. I have seen
comparable cookbooks that deal with Chinese breads, buns and pastries.
In English would be preferred - but one in Japanese with good
illustrations or photos and a clear, step-by-step layout would work
out.

Thanks,
