I bought this lemon crumble muffin one morning on my way to work. It was very nice – in muffin itself there were streaks of tangy lemon curd, and there was sweet crumble peeping through the top of the muffin. But don’t you think the lumps of crumble make the muffin look kind of diseased? If you didn’t know what “crumble” was (e.g. in the context of apple crumble), I don’t know if you’d want to buy a lumpy muffin like this… :-P
