Well I just started the mash for a half batch of this. I got a kick out of weighing my Minute Rice and adding it to my grains.
I am doing BIAB in a turkey fryer. So here's how I think my process is going to go.
Mash in 4 Gal. of water at 152.
Put lid on and wrap up with two blankets and a sleeping bag.
Trust that that will do well enough for the mash, and RDWHAHB.
About 20 minutes before the end of the mash, use spare pot to bring 3 Gal of water up to 168.
When mash is done, Lift and drain bag, then "dunk sparge" in the 3 gal pot.
Bring the 4 gallons to a boil, deal with hot break, add some from 3 gal pot, deal with hot break, watch like a hawk, repeat till all the wort is in the turkey fryer pot, and boil.
Sound reasonable?
