Mr. Beer BoosterContrary to the instructions I started a 2-gallon boil rather than the recommended 1-gallon. Here I'm adding the "Booster", which is a granulated mix of mostly dextrose (corn sugar) and dry malt extract. The liquid malt extract included with the kit is made from a mix of malts so there's no steeping, and pre-hopped so there's no hop boil. I poured in the liquid malt mix and then gave it a 20-minute boil anyway.
