Of all the lagers I've made, this is the closest to commercial pilsners and is very similar to Peroni, Budweiser, Corona etc. It benefited from spending a few weeks in an outdoor shed in winter - a few freezing nights helped make it very bright and clear.
To make the lager dry and crisp, the recipe uses quick-cook rice and quick-cook polenta (the nearest things I could find in the drop-down menu were "flaked rice" and "grits", but I didn't use these). Because these adjuncts are "quick cook", they don't need a cereal mash - they just need to be cooked to make them mushy and expose the starch.
First prepare your water (profile light colored and malty). Then take a few litres out of it to boil the rice and polenta as per intructions on the packet. Let the pan of mushy rice + polenta fall to strike temp and simply tip it into the tun with the mash water at same strike temperature. Easy.
I did a full-volume mash for convenience and to save time. Efficiency will be a bit higher if you sparge.
