Now that was a good and glorious fad. Before the wedge of lime in a bottle boom limes were a hard to find commodity in Europe.

As a result of it, limes have been incorporated into mainstream Britain. This makes it so much easier to make all manner of other drinks (caipirinhas especially) and foods. Very, very useful fad.

Frozen yogurt has taken a long, long time to fully percolate into the UK and Spain. Ben & Jerry's version has only recently made it to the supermarkets here in any noticeable way.

I'm holding out for a Frozen Custard fad, I'm probably in for a long wait.
