I've been inspired to write this by a post by the wonderful Lynn Price in Behler Blog, where she asks 'is your main character vanilla?' She says 'I'm not a fan of vanilla.' I know what she means, but I want to stand up for vanilla.
I think it is the most fantastic flavour - subtle, yet deep. The trouble is we're used to stuff called 'vanilla ice-cream' that doesn't really taste of vanilla. Eat something with real vanilla in it and it's a different taste experience.
