Here's what we are working on right now. I'll be able to report back around Christmas as to whether it's any good.
Also, we're fairly new at this.
We started with a 5 gallon milk stout recipe. To make it our holiday beer, we added one pound of brown sugar and one pound of Hershey's cocoa powder right at the end of the boil--just long enough to dissolve them. Then we're going to add 5 lbs of canned, pasteurized Oregon tart cherries to the secondary this week. I don't yet know if we'll puree them or put them in whole.
I hope it turns out well. I think it will probably be OK.
