So, as I'm makin' my beer last night I got to wonderin' about something. I bring some water to boil, pull from heat to add LME (learned the hard way) and return to heat once it's all pretty much dissolved. I had turned the burner down to @ 75% while I was off of it, forgot to turn it back to full. Set timer for 10 minutes for 1st hop addition. 10 minutes comes and goes, add hops, NOW I set back to high, reset for 35 min for next hop addition. 8 minutes into this phase, or 18 minutes since I put it back on the heat, I get back to a full boil. I finish the regularly scheduled timing as if it'd been boiling the entire 60 minutes, but wondered if I need to wait for a proper "Boil" to start the clock. It was definitely hot & steamy the whole 60 minutes, just not at a full, rolling boil. Is it essential to boil, or just be real, real hot?
