Step 5.5 (EDIT)
Pour the wort from your original mash into the pot with the sparge water (now wort as well) or vice-versa. Try to minimize splashing, but don't worry about it. Put your heat to high and proceed to Step 6.
Step 6:
As the water heats up, i add my extract. Some people wait until it boils, then remove from heat and add, but i find my method makes it quicker with no undesirable effects...just be sure to stir well. I add all my extract at the beginning of the boil.
Step 7:
Start your boil as usual! I reuse the grain bag for the hops...less to clean overall and it keeps me cleaning as i go. I'll clean the rest of the pots at this point too...i need the sink free. I use the binder clips again (be sure if you have a gas burner that you keep that nylon bag from going over the side and setting on fire.)
I use a partial boil, and adjust my hops accordingly, shooting for the middle or top of the style.
Step 8:
Cooling...i use a water bath in the apartment. i change the water out 3 times over about a half-hour period...the last time i will add ice to speed it up.
Step 9:
Sanitization...I use iodophor or star-san. I sanitize anything that could possibly touch the yeast or the wort, in this case my two 2.5 gallon carboys, my airlocks, my sampler, my funnel and i even throw the yeast packets in there.
NOTE: This solution is a little heavy...your iodine water does not need to be this dark. Use the manufacturer's recommended dosage.
