At the bottom is supposedly the original "north star" homebrew recipe from which sculpin IPA was based on.
Watch: https://www.youtube.com/watch?v=I_11Yn7V9UM
for a little video at Ballast point.
If you want to use dry malt extract then login to this recipe at http://www.brewersfriend.com/homebrew/recipe/view/236441/sculpin-clone
and adjust the fermentables. (and get rid the of the dextrose).
Aim for 1.067 OG and 80+ IBUs and 7% ABV.
I've substituted Hallertau NZ (wakatu) for the Hallertau Northern Brewer in the recipe below.
White Labs WLP001 is the yeast to use.
(I'm too cheap to buy it and it's too old by the time it gets to NZ)
In the video you see the amarillo added to the whirlpooling wort after flameout.
I'm going to boil it for a minute but you might want to add it after flameout and let the wort sit (covered) for 15 mins, (give it a stir to "whirlpool" it a bit).
I'll also do the wort in 2 batches as I only have a 15L stock pot.
(1st batch with all the steeped grains)
Will add the dextrose when aerating the wort, not in the boil.
Mash at 150 for 90 minutes. Boil for 75 minutes.
