I've never done this before, but I'm planning on doing it this weekend. My question is, I've left the cake sitting in the carboy (sealed) since Sunday when I racked off of it...so would it be helpful to pour a small starter batch into the carboy the night before I brew? Or is this unnecessary? If it hadn't been 2 weeks since the original pitch, and it hadn't been sitting alone for a week, I might not be so concerned, but in terms of decreasing lag time as much as possible, wouldn't a small starter poured onto the cake the night before serve to jumpstart the cake? Or is this completely unnecessary?
