The base flavor of candy – sweetness – comes from sugar. Technically sugar is in the form of sucrose, glucose and fructose. These are basic molecules. But just because the chemistry may give the impression that one sucrose is the same as another sucrose, don’t let that fool you. Not all sugar is created equal.
Sugar can come from many sources. Corn (for corn syrup), sugar cane, and sugar beets are three of the most common sources. At Zingerman’s Candy Manufactory, we stick mostly with cane sugar – more on that in a moment. But there are other sources, too. For example, it’s traditional to make sugar made from maple tree sap that has some of the wonderful flavor you find in real maple syrup.
Brown cane sugar is the most common sweetener at Zingerman’s Candy Manufactory. But not all brown sugars are the same, either! Standard supermarket brown sugar is fully purified white sugar coated with molasses to make it brown. The purification process involved many filtration stages involving phosophoric acid, calcium hydroxide and activated carbon or bone char. I don’t even know what bone char is, let alone why it’s part of making brown sugar! You can spot the ruse when you rub some between your fingers. The molasses will come off and the crystals will show their white underbellies.
The brown sugar we use, called muscovado, goes through minimal processing. Essentially, it is refined to the point where it isn’t totally dark (molasses sugar) and not yet white (white sugar). The flavor difference between it and the standard varieties is immense.
You can buy both types of sugar and taste them at home. The standard brown sugar will be sweet with little flavor. The muscovado will be sweet, but it will also have the wonderful aromas and flavors of molasses. Its flavor will last longer too.
When we make caramel at Zingerman’s Candy Manufactory, we can choose which sugar to use. Muscovado is more expensive, but the caramel resulting from using muscovado is richer and more complex so we use that. You really can taste the difference. Large candy bar companies cut costs and use cheaper sugar – for caramel, usually flavorless refined white sugar cooked til golden.
A final quick note. We also use corn syrup (regular, not high fructose) to make caramel – for texture. It makes the caramel very smooth.
