Thanks for explaining Zymurg. I've made invert before and may try adding some acid in my next trial then. I'm guessing this crystalized batch is still good to use, but its 280F medium amber and I think a 290F dark amber will go well with the beer I have planned. Good excuse to make another pound anyway.
Not sure, but I may have interpreted the second water addition part incorrectly. I assumed I was supposed to steadily pour ALL the water in at once after reaching desired temp, letting it free fall and then reheating to 240. Reading pg 9, I noticed someone explain this water should be added slowly until the temp drops to 240... and then stoppimg immediately. Which way is right?
I do it the first way. Bring it to your desired temp, add the water (a little at a time so it doesn't jump out of the pot), it'll drop down to 212ish, then reheat until it gets to 240. I often add some more water so it is thin enough to pour when cool. I seal it in mason jars for use later.
