EDIT: I left in some of the directions for the extract recipe in the instructions below. Notice, no cold water need be added at the end of boil if you end up with 5.5gal.
Love Old Rasputin. I haven't tried this yet but I have the recipe ready to go this weekend. Hoping it is as good as it looks. It has a touch less of each of the roasted grains.

Old Rasputin Imperial Stout (clone)
5 gallons, extract with grains
OG = 1.090 FG = 1.022 IBUs = 85-95 ABV =9%
Ingredients
14 lb Pale 2 Row malt
1.0 lb. Hugh Baird Carastan malt
0.5 lb. Hugh Baird Brown malt
0.5 lb. chocolate malt
1.0 lb. crystal malt (120° L)
0.25 lb. roasted black barley
22.7 AAU Cluster hops (bittering)
(3.25 oz. of 7% alpha acid)
9.0 AAU Northern Brewer hops
(aroma hops) (1 oz. of 9% alpha acid)
8.8 AAU Centennial hops (aroma)
(1 oz. of 8.8% alpha acid)
1 tsp Irish moss
White Labs WLPOO1 (California Ale)yeast or Wyeast 1056 (American Ale) yeast
0.75 cup of corn sugar for priming
Step by Step
Mash all your grains at 152° for 45 minutes. Collect enough wort to boil for 90 minutes and have a 5.5 gallon yield. Decrease the amount of bittering hops to 2.75 oz. of Cluster to account for the increased hop extraction efficiency in a full boil. Add the Cluster (bittering) hops and Irish moss and boil for 60 minutes. Add the aroma hops (Northern Brewer and Centennial) for the last two minutes of the boil. Cool the wort to 80° F, aerate the beer and pitch your yeast. Allow the beer to cool over the next few hours tó~ 68-70° F, and ferment for 10 to 14 days. Bottle your beer, age for two to three weeks and enjoy! (Yes, that's right, this beer so well- balanced that North Coast releases it to the public in less than a month.)
