My last few batches have been partial mash. I have been using more grains and less extract. I am not looking at my notes, but my last few were around 5 pounds two row, 1 pound of specialty grains and 3 pounds extract. I used a grain bag and stainless steel pot in the oven for an hour. Heated water to 160'ish, added grains and stirred and temp hit 151. I then placed the pot in the oven which was preheated to 200, and then turned off. I sparged with enough 170 water to fill up my boil pot enough for a good boil.
Grains are cheaper than extract, so if I am going to do the extra effort to mash rather than extract with steeping grains I like to use more grains and save a couple bucks.
