What Blessing Did Jesus Say at the Last Supper?

A listener named Brian asks Father Dave about a specific part of the Eucharistic Prayer. “The words of the consecration say that Jesus took the bread, said the blessing, gave it to his disciples, and it ends with ‘do this in memory of me,’” Brian begins. “My question is, if Jesus said the blessing, and I assume that blessing they referred to was something standard in the Hebrew tradition, why is that blessing not part of the Eucharistic Prayer?”
