Tempering Chocolates the Manual Way
Luster, snap and the rich texture of chocolates are acquired qualities, and come about when chocolates undergo tempering. Though conching can refine the particles of chocolate liquor, only tempering can make them undetectable by the tongue.
Besides a shiny patina, smoothness and a longer shelf life, tempering of chocolates also prevents blooming. If blooming is allowed to affect chocolates, grayish-white spots of cocoa butter crystals on chocolate surfaces will appear, making chocolates impossible to sell.
Chocolates get distempered at temperatures over 90F so when you melt chocolate to get them ready for candy-making, you essentially need to temper again.
Chocolatiers may be forced to do manual tempering on certain emergency situations, such as a blackout, so manual tempering must be an acquired skill for all chocolatiers though they have tempering machines to facilitate the tempering of large quantities of chocolates.
Tabliering, one of two manual tempering techniques, has its roots in France. There is a reason for its alternate name of marble-slab technique because you temper melted chocolate by cooling it to proper temperatures on a marble or stone slab.
In tabliering, one pound of chocolate is chopped, melted, and then divided into two afterward. One half is first used for tempering by cooling it down by spreading and folding crosswise on a marble slab. After the mush has achieved a thicker fluidity and a matte sheen, you put in the other half and do the same thing over again until the whole mush achieves the same cooled down characteristics.
It is the same procedure in “seeding”, the other manual tempering technique, but chocolate pieces tempered by the manufacturers, serve as models or “seeds” for a proper tempering. A fourth of the chocolate is mixed in with the rest of the chocolate, which is melted, in a bowl. The objective is the same matte sheen and thick fluidity as in tabliering.
Specific temperatures should be kept even with the utmost accuracy in both tabliering and seeding. An accurate thermometer can be used for this. The tempered chocolate can be made into fruit-filled chocolates or chocolates of assorted sizes and shapes.
Manual tempering could be very complicated and intricate as it requires your full, undivided attention. It may take away the fun out of crafting chocolate confectioneries. A tempering machine will offer you plenty of experimenting time with your chocolate as well as in bringing your business to the next level.
