‘ is not what you throw in the air at parties in Italy – those are called ‘coriandoli’. In Italy, confetti are candy-covered almonds that Italians give out at weddings (also known as Jordan Almonds).
Tradition (and superstition) says that you put an odd number of confetti in a little sack and tie it to a wedding favor for each guest to take home. There is a little tag inside the sack with the bride and groom’s name and the wedding date on it.
This wedding tradition dates back to Roman times when almonds were honey-coated (no sugar until the 1400’s) and given out at weddings and baptisms.
In Byzantine Venice, confetti were tossed off balconies during carnival parades (auth: maybe this is where the mix up started between confetti and coriandoli).
There should always be an odd number of candies in each sachet symbolizing the indivisible nature of marriage.
