These are the cakes part of "Cakes and Wine." They can be any form of goodie that the group desires, usually something reflecting the reason for the celebration. Shown here are gingerbread cookies.
Traditionally, there is one for each celebrant, and one left over. (This group has six people.) The "extra" one is actually used first, and goes into the Libation Bowl, with each celebrant in turn taking one as the plate is passed.
They show the fruitfulness of the Earth, and also the goodness of life.
These cakes all get eaten during the blessing. If there are any left (an expected celebrant can't make it at the last minute, or an allergy is discovered) the celebrants may share them among the group, or they may be added to the libation bowl.
