I knew I was forgetting something. Instead of stirring my priming sugar into 16 oz. of boiling water ( for a 5 gal batch), I dumped the sugar into the bottom of my bottling bucket and then siphoned the brew in on top of it . I did give it a gentle 2 min. stir. When I was done racking, I saw maybe a teaspoon( out of 5oz.) of sugar on the bottom of the bucket that didn't dissolve. What I'm most worried about is contamination from the corn sugar. I don't think the lack of the 16 oz. of water will matter that much. Any opinions appreciated. thanks
