The Bible is silent on the matter, largely because it is not a liturgical manual. A diversity of practices existed in the ancient church. Indeed, even in the modern church, the clergy receive in separate forms and receive the body of Christ in the hand. However, if you've observed the rite for doing so, you would perhaps understand why such is probably not a reasonable method in modern times to dole out communion to the laity. It's very cumbersome to do properly, particularly when the host was leavened and all particles taken from the same host. The exact practice of intinction and spooning it out is a pastoral and liturgical matter rather than something dictated by divine law.
