I don't know why I didn't do this years ago. Maybe because "How to Brew" recommends drawing off part of the mash with a pitcher and pouring it back into the mash tun to vorlauf. Today, for some reason, it hit me that this would introduce hot side aeration and I have a perfectly good March pump, so I used it. It was much easier and less sticky than using a pitcher. I'm frequently amazed at how long I can go before an idea occurs to me. The worst part is, I brew with people who recirculate with a pump during the mash and still didn't think to do it.
