Tempering is a precise heating and cooling process that aligns the cocoa butter crystals in chocolate into a stable crystalline structure (specifically Form V crystals). Properly tempered chocolate has a glossy, smooth surface, breaks with a clean snap, contracts slightly for easy mold release, melts evenly on the tongue, and resists bloom (white streaks or patches) during storage. Tempering is essential for producing professional-quality chocolate bars, including Dubai chocolate.
The basic tempering process involves three temperature stages: melting the chocolate fully (to 131°F/55°C for dark, 113°F/45°C for milk or white), cooling it to a working temperature (82°F/28°C for dark, 80°F/27°C for milk or white) while agitating constantly, then gently rewarming to the final working temperature (90°F/32°C for dark, 86°F/30°C for milk or white). Common methods include tabling (spreading on marble), seeding (stirring in finely chopped unmelted chocolate), and using a sous vide for precise temperature control.
