Title says it all, that's what I want to brew next. I am looking for advice on a range of things: 1.) Any good porter recipes to use as a base for this brew? 2.) How shall I incorporate the sweet potatoes? Puree them (like I make my sons baby food) and add it to the boil, to the primary, to the secondary? Roast them first? Roast them with spices? 3.) Anyone ever do a brew like this before? I'd love to hear about your experience. I am doing extract brewing. Thanks in advance! I truly appreciate the info and advice I get from you all.
