Yosef Karo, Translation:Shulchan Aruch — 158 Laws of washing the hands for a meal
“ You could even bless before drying your hands because the drying is also part of the mitzvah. If you forgot to bless until after drying, you can make the blessing then. 12 Dry your hands well before breaking bread, because one who ate without drying his hands is as if he ate contaminated bread. 13 One who dunks his hands [in a mikvah] can eat [bread] without drying [his hands] . The same is true if he washed both hands at the same time with a reviis of water, or if he washed one hand then poured a reviit in it and poured it on the other hand. ”
