From something I picked up on the old HBD back in the late 90s early 2000s timeframe, as to mix a campden tablet into the mash. The SO2 is an antioxidant that inhibits the oxidation of the malt compounds that lead to stalling. Any remaining SO2 is driven off in the boil.
I'm going to buy some campden tablets! Thanks!
