My parish is a large, suburban one, with 5 Sunday Masses, a Sat. vigil, and 2 daily Masses on each weekday. Novus Ordo, and it’s 100% intinction at every Mass.
Without arguing each technical point, here’s how it’s done in my parish:
The priest, deacon, and any EMHCs (along with altar servers with the–forgive me, I’m blanking–metal item to catch any hosts that fall) all stand with intinction sets. (Kind of a mini-cup set into a saucer–precious blood in cup, blessed sacrament around the cup)<—as described above by PP.
Communicants desiring only the Blessed Sacrament, or those who wish to receive by hand come up extending their hands.
Communicants desiring both (by intinction) come up with arms crossed across chest, and receive on the tongue.
Obviously, no reception by hand with intinction.
Cleaning the vessels used takes a little more time than usual(3-5 minutes, tops?), but it’s nice to have that time for prayer and a bit of a pause before the concluding prayers and dismissal.
