I use the Campden to neutralize chloramine in my tap water. You may not need to use this.
Mash in with 8 quarts of water (1 quart per lb of grain) for a target temp of 154 degrees. Rest for 60 minutes, then sparge to collect 6.5 gallons. With my system I get about 1 gallon of boil-off over an hour, however you may need to adjust the recipe to match my numbers.
Overall it's a good light but malty session beer without too much bitterness or strong hop character. Its best enjoyed around 55 degrees. From a visual standpoint the flaked barley produces some chill haze at lower temps, and the flavor is also muted if drank colder than cellar temps. I force carbonate to around 1.9 volumes CO2 (12 PSI at 55 degrees).
