It is your beer, do what you want. If it were me (as a quick assessment) , I would:
- Dump the spice pack in the trash (or save it for a future Saison ... that probably will not happen).
- Add 8 ozs Crystal (C60 or C80)
- Add 1.5 lbs of DME or 2 lbs LME (lightest you can get)
- Add 0.5 lbs table sugar (to help dry it out a bit, maybe 0.75 lbs).
- Grab 3 ozs the hop of your choice, Cascade, Centennial, Chinook, Citra, etc. And add 0.5 at 60, 0.5 at 10, 0.5 at 5, 0.5 at flame out, and 1.0 at dry.
