Two years ago inspired by the BBC TV series the Great British Bake Off (#GBBO for those double screening - and if you do check out the suggestions for #MaryBerryHarryPotterTitles) I baked the humble ship's biscuit.
Since then I have been undertaking an experiment on its durability. Would it really be edible to a hungry crew undertaking a circumnavigation in the great days of sail months if not years later?
The answer at four months, six months and then one year were all positive: the biscuit might be tough and lacking in flavour but it was sustaining and enduring.
So how about after two years? Well just now I ate the last of that batch and it tasted as bland as all the others had, so I guess that counts as a success.
There are no more ship's biscuits left, that tin is empty, and to be honest I'm not planning on repeating that experiment.
There are other more interesting things to bake:
But its good to know I could bake for a long offshore sail should I have to.
