The recent thread on chain letters reminded me of the craze to make friendship cakes in the 1980s. If I remember correctly it was a yeast cake you had to feed for a couple of weeks, then you baked the cake but passed some of the starter on. By the time it got to me the entire primary school had been given starter and everyone was sick to death of the cake. There was a variation involving a "ginger beer plant".
Does anyone else remember this?
