NO need to boil honey. I was a honey addict when I started, did like 50 batches. I've added it every which way, to the mash, boil, flameout, primary, secondary, bottling.
I just added it straight. Never had any issues. Make sure its real honey that you are using. Google "fake honey" to see what I am talking about
Honey will only come through in light beers, and its subtle. No worries with a black IPA, the hops and roasted malts will completely mask it. I've only had noticeable results with pale wheats, adding the honey to the primary at the tail end of fermentation and primed with it. And its was pretty subtle. Suprisingly, when you cracked a bottle, you got the aroma the most.
