How to Temper Chocolate
Tempering chocolate means melting and cooling it to specific temperatures so cocoa butter crystals form properly. This gives chocolate a shiny finish, crisp snap, and prevents white streaks called bloom.
Why it matters
Properly tempered chocolate contracts as it cools, releasing cleanly from molds. It stays solid at 70F room temperature. Untempered chocolate feels soft, melts on your fingers, and develops gray streaks within 24 hours. Professional chocolatiers temper every batch.
What you need
Steps
Chop chocolate into pieces smaller than 1/4 inch. Reserve 25% in a separate bowl. Place 75% in your double boiler over 1 inch of barely simmering water. Stir every 30 seconds until chocolate reaches 115F for dark, 110F for milk, or 105F for white chocolate.
Remove bowl from heat immediately when target temperature hits. Wipe bottom dry. Add half your reserved chocolate. Stir constantly in figure-8 patterns for 2 minutes until pieces start melting.
Add remaining reserved chocolate gradually. Keep stirring until temperature drops to 84F for dark, 82F for milk, or 80F for white. Chunks should disappear completely. This takes 5-8 minutes.
Place bowl back over warm water for 5-10 seconds. Remove and stir. Repeat until dark chocolate reaches 88-90F, milk reaches 86-88F, or white reaches 82-84F. Never exceed these temperatures.
Test temper by spreading a thin layer on parchment. Properly tempered chocolate sets within 3 minutes at 65-70F room temperature, looks glossy, and snaps when broken. If it stays soft or streaky, repeat from step 3.
Work quickly once tempered. Keep chocolate between working temperatures by placing bowl over warm water for 5 seconds every few minutes. Stir after each warming. Use within 20 minutes or re-temper.
Common Mistakes
Overheating chocolate above 120F
What happens: Chocolate seizes into grainy clumps that won't melt smoothly
Fix: Use thermometer constantly and remove from heat 2 degrees before target
Getting water in chocolate
What happens: Even one drop causes chocolate to seize instantly
Fix: Dry bowl bottom before moving and keep steam away from chocolate surface
Cooling too slowly below 84F
What happens: Wrong crystal types form, causing dull finish and soft texture
Fix: Stir constantly during cooling phase and add seed chocolate in small amounts
Using chocolate chips instead of bars
What happens: Chips contain stabilizers that prevent proper tempering
Fix: Buy chocolate bars or couverture with cocoa butter content listed on package
Troubleshooting
Chocolate has white or gray streaks after setting
Then: Remelt to 115F and start tempering process again from step 1
Chocolate won't harden after 10 minutes
Then: Temperature dropped below 80F or rose above 90F during work. Add 2 oz properly tempered chocolate and stir until combined

FAQ
Can I temper chocolate in the microwave?
Yes, but success rate drops to about 60%. Microwave at 50% power in 15-second bursts, stirring between each. Stop when chocolate reaches 100F, then follow seeding steps. Microwaves create hot spots above 120F that ruin batches. A double boiler gives you better control and consistent results.
How long does tempered chocolate stay good?
Properly tempered chocolate holds its temper for 6 months when stored below 70F and under 50% humidity. After tempering, chocolate stays workable for only 20 minutes before crystals start forming incorrectly. Finished pieces keep their shine and snap for months if you maintain storage conditions.
What's the difference between tempering dark, milk, and white chocolate?
Each type needs different temperatures because cocoa butter content varies. Dark chocolate tempers at 88-90F, milk at 86-88F, white at 82-84F. Dark chocolate contains 50-90% cocoa solids, milk has 25-40%, white has zero. Higher cocoa content means higher working temperatures. White chocolate burns easiest since milk solids scorch at 95F.
