Call me crazy, mad, stupid, what you will, but I'm going to give this a shot. It's based on an oatmeal stout I made for my buddy's wedding that turned out quite well so I know I have a good base here.
8.00 lb Rahr 2-row
1.00 lb Flaked Oats
0.50 lb Crystal 80L
0.50 lb Roasted Barley
0.50 lb Chocolate Malt
1.00 lb Lactose
OG - 1.063
2 oz EKG @ 60 min - 36.2 IBU
Mash at...156 or so
1 - 3.30 lb can of Oregon Raspberry Puree in secondary (+0.02 from my calcs)
1 - 1.00 lb jar of Smuckers Natural PB (ingredients: peanuts, salt), oil drained off over 2 months
I'm debating whether I should add the PB at the end of the boil or in secondary. Also I talked to Joe Short about his PB stout last weekend and he said he uses 60lb of peanuts in 7bbl (doesn't worry about the fat, "I just roll with it. It all settles to the top and I rack from under it anyway) so by my calcs my ratio is pretty close there.
Thoughts? Am I completely insane? FYI I'll be naming it:
