It is virtually impossible to torte (cut in half) a sheet cake of any size without it cracking or crumbling. A technique used by professional bakers is to bake multiple thinner layers and simply stack them between delectable icing layers to create the height you need for the cake design.
Barter is a system of exchange where goods or services are directly exchanged for other goods or services without using a medium of exchange, such as money. It is distinguishable from gift economies in many ways; one of them is that the reciprocal exchange is immediate and not delayed in time.
Barter, the exchange of one good or service for another, is a form of payment. The most common means of payment involve use of money, cheque, or debit, credit or bank transfers. Payments may also take complicated forms, such as stock issues or the transfer of anything of value or benefit to the parties.
