I really thought candied ginger would be easy. Slice up some ginger, blanch it, put it in a pot with equal parts sugar and water, and heat to 225°. Straightforward, precise directions. I even had a thermometer — not a candy thermometer, but an accurate instant-read meat thermometer that I figured should do the trick.
You can see where this is going. After blanching, three hours of boiling, overnight soaking in their syrup, then individually fishing out the ginger coins and laying them on a pan to dry all afternoon, my ginger slices were all wrong; grainy and wet and crystalized. Sure, they were still delicious, but where were the chewy, golden, translucent coins with just a hint of stickiness that I'd expected?
Here's the thing, though. Just for the heck of it, I poured half of the gingery syrup back into the pot, then blanched a bunch of lemon peels and tossed them in. An hour later I had beautiful strips of perfectly candied lemon peel without even a hint of graininess. What happened?
As far as I can tell, there were two key differences: temperature and interfering agents.
