Hey Zifferent,
Try 6 lbs. of Lt. Malt, 1 lbs. of crystal 40L, 1 lbs. Dextrin Malt
steep grains in 2 gals. of cold water, slowly heat to approx. 160 deg. for 10 mins., toss grains,add DME and stirr well, bring to boil and add hops as in all grain recipe, follow all grain recipe to finish. Sorry for not adding this before, I hope this helps.
Happy Brewing,
