Tempering Chocolate
Tempering is the process of melting chocolate to specific temperatures to realign its cocoa butter crystals. When done correctly, the result is chocolate that sets with a sharp, clean snap, maintains a stable sheen, and releases easily from molds without turning grey or dull at room temperature.
Control is the only variable that matters.
Work in a cool, dry room. Even a drop of steam or a humid day can cause your chocolate to seize and turn into a grainy, unworkable paste.

The Temperature Dance
You are melting the crystals to break them down, then introducing solid 'seed' chocolate to force the cocoa butter to reform into the stable Beta-V crystal structure.
The method.
Melt the base
Place two-thirds of your chocolate in the bowl. Heat until it reaches 115°F (46°C) for dark chocolate, or 110°F (43°C) for milk or white. Do not exceed these temperatures or you will scorch the solids.
Seed the chocolate
Remove from heat. Add the remaining third of the chocolate to the bowl. Stir constantly and slowly to avoid incorporating air bubbles. The goal is to melt the solid chocolate into the liquid mass, which pulls the overall temperature down.
Cool to working temperature
Continue stirring until the temperature drops to 88°F–90°F (31°C–32°C) for dark chocolate, or 84°F–86°F (29°C–30°C) for milk and white. The chocolate will thicken slightly and gain a noticeable gloss.
Test
Dip the tip of a knife into the chocolate and set it aside for three minutes. If it dries with a smooth, firm, non-streaky finish, you are ready to dip or mold.
When it doesn't go to plan.
Keep a bowl of warm water nearby to quickly bring the temperature back up if it drops too low while you are working.
Never let even a speck of water touch the melting chocolate; it will cause it to seize instantly.
Use high-quality couverture chocolate; the higher cocoa butter content is essential for a proper snap.
The ones that keep coming up.
What does it mean if my chocolate has white streaks?
Those are cocoa butter crystals that have bloomed. It means the chocolate was either not tempered correctly or was stored in a space that was too warm.
Can I re-temper chocolate that has failed?
Yes. Simply chop it up and restart the entire process from the melting stage.
