Verdict: Guinness gingerbread cake

In the end, I was bothered enough to make custard, but not patient enough. In cooking off the custard to thicken it, I heated it a little bit too quickly and ended up scrambling the eggs. D'oh! Never mind - Instant custard to the rescue!

Anyway, the cake: Pretty good actually. I liked the slight bitterness from the Guinness and the overall flavour was really good. Texture was just like a moist sponge cake really, and the crust was beautifully crisp but not hard, so all in all a decent success I'd say. Pity about the custard...
