classic ship's biscuit. It is fair to say it wasn't a great success, the creation having the strength and taste of mahogany.
I put some aside to test their endurance and as can be seen by the photo above they seem to be surviving just fine. Having just tried one I was actually pleasantly surprised, as my sample wasn't as inedible as I remember - indeed I have to confess to scoffed it all without even a glug of rum to dunk it in.
They seem to have softened with age - or is it me?
I have three remaining and have returned them in their tin back to the cupboard to be re-opened at some future date.
