Ive been trying to mill grain with a meat grinder, but even with a plate with the smallest holes i get quite big pieces of grain at the end. I need a device like a mill to make it into homogeneous paste; but even if took a mill, i dont think it would be suitable for this job, because it is for dry grain and mine is wet. Im thinking about getting a big heavy antique brass mortar with pestle; will it do the job?
