How to temper chocolate for shiny molded candies using the seeding method
Tempering chocolate ensures your molded candies set shiny, crisp, and with a good snap. This guide walks you through the seeding method — an accessible, reliable technique that uses pre-crystallized chocolate to coax proper cocoa butter crystals into melted chocolate.
Step 1: Prepare equipment and chocolate
Gather a heatproof bowl, saucepan for a double boiler (or a microwave-safe bowl), digital thermometer, spatula, a baking sheet, and clean molds. Use high-quality couverture or chocolate chips; measure about 500 g total chocolate so you have room to seed with roughly 100–150 g of solid chocolate.

Step 2: Chop chocolate evenly
Finely chop about 350–400 g of the chocolate you will melt, keeping roughly 100–150 g back as seed chocolate. Smaller, uniform pieces melt more evenly and cool faster, helping control temperature precisely.

Step 3: Melt two-thirds of chocolate
Place the 350–400 g of chocolate in the heatproof bowl over barely simmering water (simmer, not boil) or use the microwave at 50% power in 20–30 second bursts. Heat dark chocolate to 45–50°C (113–122°F), milk chocolate to 40–45°C (104–113°F), and white chocolate to 40–43°C (104–109°F). Stir frequently and avoid steam or water contact.

Step 4: Cool to tempering range
Remove the bowl from heat and let it cool while stirring to bring temperatures down to the tempering working range: dark 31–32°C (88–90°F), milk 30–31°C (86–88°F), white 28–29°C (82–84°F). Stirring speeds cooling and aligns crystals.

Step 5: Seed with chopped solid chocolate
Add the reserved 100–150 g of finely chopped seed chocolate to the melted chocolate and stir continuously until fully melted and the mixture stabilizes at the working temperature. The seed provides stable beta crystals to guide the chocolate into temper.

Step 6: Test for temper
Dip a small piece of waxed paper or the edge of a spoon into the chocolate and set it on the counter for 3–5 minutes. Properly tempered chocolate will set firm, glossy, and with a clean snap; if it looks dull or tacky, gently warm to melt a few degrees and repeat seeding.

Step 7: Pour into molds and cool
Working quickly, pour tempered chocolate into clean molds, tapping to remove air bubbles, and scrape excess. Allow molded candies to set at room temperature in a cool, dry place (16–20°C / 60–68°F) for 30–60 minutes or refrigerate for 10–15 minutes if necessary. Unmold when firm and glossy.

- Use a reliable digital thermometer for accuracy to within 1°C (2°F).
- Keep bowls and utensils dry — even a drop of water can seize chocolate.
- If chocolate thickens while working, microwave very briefly (5–8 seconds) or warm over the double boiler to lower viscosity a couple degrees.
- Work in a cool room (16–20°C) to prolong working time and help proper setting.
- Maintain about 100–150 g of seed per 350–400 g melted; too little seed slows crystallization, too much can over-thicken.
- When in doubt, repeat the seed-and-stir process rather than overheating; gradual approach preserves temper.
- Never let chocolate exceed 50°C (122°F) for dark or 43°C (109°F) for white — overheating destroys seed crystals.
- Avoid water contact; even small amounts will seize melted chocolate into grainy lumps.
- Do not stir chocolate aggressively or introduce air; over-agitation can cause bloom or texture issues.
- If chocolate becomes dull or grainy after cooling, discard or re-temper — do not combine with fresh chocolate without re-melting and re-tempering.
