So far:
Tonight I pitched the yeast in the 5 gallons of must I prepared yesterday, as mentioned above. This time I added the go-ferm to the rehydration water, then put the yeast in, waited 15 minutes, and pitched it in the must. While I was waiting I aerated the must with my immersion blender. It worked surprisingly well. Mine has a detachable plunger part that is submersible, so I put the whole thing into my sanitization solution, then soaked it in clean water and rinsed it thoroughly. The yeast was very happy and smelled much like yeast. OG: 1.090, as near as I could tell. It's a bit warm in here, though, and I don't know how that affects the reading. Temp in the kitchen was around 78, as was the must.
I also put together a batch of JAO, following the directions as closely as I could manage. 2 lbs Sue Bee "Aunt Sue" Raw Honey, 1.5 lbs Sue Bee Orange Blossom Honey, 1 moderately small orange, 2 cinnamon sticks (they were small, and I like cinnamon), 2 cloves (ditto, very small compared to other cloves I've seen. And I like cloves

), dash of nutmeg, and 2 whole allspice (didn't have any ground, and they're kind of small). Shaken, yeast... oops, no reading for OG, considering that my hydrometer thingie was still full of the 'real' mead must. Oh well... it's supposed to be foolproof, right?
Waiting for tomorrow: another 1 gallon jug, currently full of apple juice. I'm thinking that I will use part of the apple juice, a chopped up apple, cinnamon stick, cloves, raisins, nutmeg, allspice, maybe a vanilla bean if I can find one. If not, a splash of mexican vanilla extract. This time, all the honey will be the Aunt Sue stuff. I tasted both as I was adding them to the JAO, and the orange blossom turns out to be the same stuff my mom made sandwiches with as a kid (PB & Honey, because I wouldn't eat any kind of jam). It was not really to my liking, and makes me glad I didn't spring for all Orange Blossom.
Now, to ask more questions... off to the appropriate fora
