Do people for reals buy HFCS for home baking? Like you can just go buy a jug at the grocery store? I've seen it in ingredients lists of packaged foods, but I've never seen the stuff itself IRL. (Gonna assume it looks roughly like syrup. Corn syrup maybe.)
The processing causes the glucose to break down into fructose, which is perceived as sweeter. In the end, it's just different types of sugar in syrup form.
