Mill the grains and do a Hochkurz step mash: Start at 144°F (62°C) and rest 30 minutes; raise to 158°F (70°C) and rest 30 minutes; then raise to 168°F (76°C) for mash out. Recirculate until the runnings are clear, then run off into the kettle. Sparge and top up as necessary to get about 6 gallons (23 liters) of wort, depending on your evaporation rate. Boil for 60 minutes, adding hops and finings according to the schedule. After the boil, chill the wort to 60°F (16°C), aerate, and pitch the yeast.
