I wanted to try the northernbrewer Jamil's Evil Twin recipe, but I couldn't wait on shipping since I wanted to brew today. I went to my lhbs and picked up the 7lbs of Muntons light DME and the hops listed in the northern brewer recipe. I also picked up the specialty grains, but my lhbs didn't have the .25 lbs of Pale Chocolate. Will this be a problem? Also, should I add all of my dme late in my boil or early or should I do some early and some late?
