Yep, that works.. A lot of the 5g kits come with 5oz of corn sugar to use just that way. Dissolve it, bring it to a boil to sterilize, and then mix it with your beer just before you bottle. I don't know if you use any sort of bottling bucket with your kit.. if not be careful not to disturb the trub in the bottom as you add the sugar-water.
I've only used the priming sugar from the kits so far, but this time I'm going to try cane sugar. In the calculator link that was provided, you'll see "Sucrose".. that is common table sugar. I think I've read in previous posts that Cane sugar works better than Beet sugar, so you may need to pay attention to packaging, but it'd be a lot cheaper than corn sugar.
Maybe someone who has used table sugar can chime in?
I used pure cane in my first (2) 5 gallon batches. It's working great so far. I was drinking it a week after bottling, and it's carbed enough, getting better every day. It took the kit carb drops 2 weeks to even get halfway there. Sam's and Costco both have 10 lb. bags of organic pure cane for less than 5 bucks. I haven't done the per oz. cost on that but it's somewhere between dirt cheap and free. I only used it because we had it in the house and everyone thought it tasted like molasses but me.
