Should the grain or strike water be added to the mash tun first?
Should I add water first, then grain? Grain, then water? Both at the same time?
I'm worried that adding grain to hot water might expose some of the grain to too high a temperature. On the other hand, adding water to grain seems like it would cause dough-balls. Combining both at once seems like you'd need at least 3 hands!
