Bamboo Charcoal Swiss Roll

When I'm out dining, I can't bake. I've been out too often to be home baking! Heehee...
This evening, I decided to do some baking, otherwise, I'll totally lose touch with baking. I've wanted to use my bamboo charcoal since I bought it from Kitchen Capers a couple of months back. I knew I wanted to try Shirley's Bamboo Charcoal Swiss Rolls when I saw her post. It got preceded by other bakes that it was forgotten...until today.
The cake turned out rather dry, but soft. I think I might have over-beaten the egg whites. However, when mixed with the fresh cream, it was still quite nice. Bamboo charcoal has this... weird and funny taste. The taste is like, when you burnt your tongue and upper mouth, and it leaves a coated layer on them. It tasted exactly like it. It leaves a layer of charred taste on the tongue. I just don't know how to describe this taste. I don't dislike it, neither do I love it. You just have to try it to experience for yourself! However, I do like this black... so cool, isn't it?
