Here is a flavour I have mentioned liberally on this blog but probably have not tasted in the last 30 years or so (in my youth my grandmother would make us treacle toffee with it – can’t remember having it since). So as soon as I saw it there on the supermarket shelf I had to get some. 

As its name indicates it is very dark in colour and despite being a refined sugar product it has a burnt bitterness to it – almost tastes like liquorice. I believe it is the main raw material used to make rum and you can certainly taste that heritage in it. A really dark flavour and one that I find in a lot of the big olorosos, amontillados and palo cortados.
