Analysis of information sources in references of the Wikipedia article "Divinity (confectionery)" in English language version.
... food historians generally agree that Divinity ... is an early 20th century American invention. ... One of the primary ingedients in early Divinity recipes is corn syrup, a product actively marketed to (& embraced by) American consumers as a sugar substitute at that time. Corn syrup was affordable (economical), practical (shelf-stable), and adapted well to most traditional recipes. Karo brand corn syrup, introduced by the Corn Products Refining Company in 1902, was/is perhaps the most famous. It is no coincidence that early Karo cooking brochures contain recipes for Divinity.
