Didn't really know how to search for this, sorry if it has been asked.
I'm doing the AHS SN Celebration clone, but I want 10 gals. I can't fit all the grains in my tun, so I thought up a great plan of doing half (5 gal) in all grain, (5g) half in extract and boiling them together. Plan seems pretty simple, catch is I don't know what to do with specialty grains from the extract recipe.
I was pondering just adding them to the AG side and compensation with the calculated water addition. Seems like a very simple answer and stupid question but some re-affirmation would be nice.
