I was living in Japan and I told my office I'd bring cakes in for Halloween, which is also my birthday. I decided on cup cakes with pumpkin in them - I'm actually a good cook and knew it would work and be seasonal.
Because I'm so rubbish at organising myself, I made them in the morning before work. So far so good, except while they were nearly done in the oven and I was washing up, I picked up a bowl with eggs in and a bowl with sugar. I'd forgotten to put them in the mixture. Being Japan, I couldn't be late for work, I couldn't not take cakes when I'd promised to, and I coouldn't buy a substitute on the way in.
I had to tough it out. I handed round my "cakes" - which consisted of just butter, flour, baking powder and pumpkin baked together - and everyone said how "unusual" they were. I said, well, this is what we eat in the UK at Halloween, and everyone smiled and thanked me and no-one asked for seconds.
I had to eat one myself, and it was like orange-coloured cotton wool.
