Though a decent temper can be obtained with a double boiler, a tempering machine is a piece of equipment used by Chocolatiers and home Chocolate enthusiasts to create the ideal Chocolate creations.

A tempering machine is designed to melt Chocolate and then bring it to set degree points while constantly stirring. Tempering machines are able to hold the temperature of melted Chocolate at a certain degree indefinitely with the aid of a temperature probe.

Tempering machines have a large bowl divided down the middle by a bowl scraper, which keeps melted Chocolate on one side and chunks to be melted on the other. It can take from 30 minutes to 2 hours to temper a batch of Chocolate, depending on the amount and the equipment, but in the absence of harsh conditions or unwanted additives, a good temper is assured. Chocolate tempering machines are not cheap, but the results cannot be beat.
