Neuske's is indeed good and fairly smokey - used to get it at a lot of stores while living in Milwaukee Used to offer butt bacon. I too would be pretty darn happy to get anywhere near their flavor.
There's been a lot of bacon discussion here during '04, maybe you've read all that already. Generally there seem to be 3 ways to go, both for curing and smoking:
Cures:
1. Kits. HiMtn seems to be most popular.
2. Homade dry cures. Jackitup posted a very straightforward method in the recipe forum; I've used it a few times and have a chunk curing now.
3. Brine cures like the scrap iron bacon recipe. Have not tried these for bacon myself.
Smoking:
1. True cold smoking.
2. Hot smoking until fully cooked. If planning to eat without further cooking, ie Canadian bacon, this is what I'd do.
3. Sort of lukewarm smoking to 125F or so.
How did you do your first bacon?
Anyhow, all this doesn't answer your question.
If using a dry cure, it'd be easy enough to either add a dry sugar like brown sugar, turbinado, maple sugar, or whatever before sprinkling it on. As to how much to add, probably quite a bit. My most recent attempt is 2 parts sugar and 3 parts salt. I used around 2 Tbsp total, so I'd have to add at least a teaspoon of sugar to make much difference. I suspect these really good Midwestern style bacons are cured with a huge amount of sugar.
I don't see why you couldn't use honey or syrup by drizzling it on after sprinkling on a dry cure.
Washing out during soaking shouldn't be an insurmountable problem. After all, it's still plenty salty. You could try painting on after soaking and before smoking, but there's so little surface area once you slice the bacon that I don't think it'll help much.
Also,
Allied-Kenco and
PS Seasonings and probably others sell "Sweeter Than Sweet Cure" intended for ham but could probably be adapted to bacon.
