In Vietnam,“Banh Phu The” is a special cake, which symbolises the loyalty of a husband and wife...

The conjugal cake is normally served at Vietnamese weddings and used as a wedding invitation or taken by the man’s family to the woman’s family on engagement day. The stickiness of the cake is said to signify the stickiness of the marriage ties. Traditionally, a guy would offer these to the girl he wants to marry. Now these cakes are still an essential part of a wedding banquet, or the gift packages that the groom's family send over to the bride's.
