My understanding is that it’s perfectly normal and expected for the priest (or even deacon) to do this when purifying the sacred vessels. I’ve seen it often–they will consume the particles and fragments and crumbs. How else would you clean a ciborium, after all?
But I think the snacking comment was about an EMHC. My understanding is that an EMHC should never do this, but instead leave it to the priest or deacon. Correct?
