Managers of the Colonial Sugar Refining Company were alert to new markets and processes. So an excited Mr Turner saw an opportunity in January 1908, and shared it with his colleague Mr Gunther:

The making of tablet sugar is a matter which we must provide for in the very near future in a way and on a scale which we have not hitherto done; what I saw in England convinced me of the possibilities of the business; so that our present appliances, small enough for our present output, will be found altogether inadequate unless we are careful to look ahead a bit.

Tablet sugar was not new. According to Wikipedia, it is

a medium-hard, sugary confection from Scotland… not as soft as fudge, but not as hard as hard candy [and] often flavoured with vanilla, whisky, or nuts. [It was] first noted in the early 18th century…

Tablet is also mentioned in Oor Wullie, a comic book focusing on a scruffy Scottish boy in a world where people speak an extreme form of Scots English.
Plans proceeded, ignoring the Scots’ notoriously bad teeth. If nothing unforseen occurs it is my intention to begin the manufacture of tablets at this refinery on Friday the 23rd instant: and for a start I propose to make ten tons per week of which quality eight tons will be packed in bulk and two tons in 2-lbs cartons.
The building was erected in 1909, to make tablet sugar, golden syrup (“cocky’s joy”) and other sugar-derived products.
