Tempering Chocolate for a Stable Snap
Tempered chocolate is the difference between a professional finish and a messy, melting disaster. It requires patience and a thermometer, but once you understand the rhythm of heating and cooling, you can dip, mold, and coat with confidence.
Control the environment first
Ensure your kitchen is cool and dry. Any water contact—even a stray drop of steam—will seize the chocolate into a hard, grainy clump.

What goes in.

Maintaining Crystal Structure
By melting two-thirds of your chocolate and adding unmelted 'seed' chocolate back in, you force the cocoa butter to align into the stable Beta-V crystal form.
The method.
Melt the chocolate
Place two-thirds of your chocolate in a bowl over barely simmering water. 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.
Introduce the seed
Remove from the heat. Gradually stir in the remaining chopped chocolate, bit by bit. This lowers the temperature and encourages the stable crystal formation.
Cool and monitor
Continue stirring until the temperature drops to 88-90°F (31-32°C) for dark, or 84-86°F (29-30°C) for milk and white. The chocolate will thicken slightly and lose its watery sheen.
Test the temper
Dip the tip of a knife into the chocolate and set it aside for three minutes. If it dries with an even, streak-free shine, you have achieved the correct temper.
Other turns to take.
Tabliering
The professional method of pouring melted chocolate onto a marble slab and working it with spatulas until it cools, then scraping it back into the bowl.
When it doesn't go to plan.
Use a thermometer you trust; a difference of two degrees can ruin the entire batch.
Keep a bowl of warm water nearby; if the chocolate sets too quickly while you are working, gently apply a few seconds of heat.
Always chop your chocolate into small, uniform pieces so it melts evenly without scorching.

What does it mean if my chocolate looks streaky?
Streaks, or 'bloom,' happen when the chocolate wasn't held at the right temperature or cooled too slowly, allowing the cocoa butter to separate.
Can I re-temper chocolate that failed?
Yes. Simply melt it back down and begin the cooling process again.
