You probably only want to add the zest of the oranges and carefully avoid the white pith. I've also had really good results with adding a little bit of orange extract that I got at the grocery store.
Also, the 40 and 30 min hop addition won't do much - maybe move 'em to 10 or flameout?
(And this recipe might turn out to be awesome but, FWIW, when I experiment with new things, I like to do a 2.5 gal batch - I've had 5 gallons of bad experiments before and it sucks.)
Who is this Rorschach guy? And why did he paint so many pictures of my parents fighting?
