How to temper chocolate for shiny, snappy molded candies using seeding method
Tempering chocolate with the seeding method is a reliable way to get glossy, snappy molded candies at home. The process uses a small amount of already-tempered chocolate to guide the melted chocolate into stable crystals, producing a smooth finish and good snap. With a few tools and attention to temperature, you can temper for molds in 15–30 minutes.
Step 1: Gather your tools and chocolate
Use a heatproof bowl, digital instant-read thermometer, rubber spatula, and clean molds. Work with 8–16 ounces (225–450 g) of couverture or baking chocolate; larger batches are fine but take longer to temper. Chop the chocolate into uniform 1/4–1/2 inch pieces for even melting.

Step 2: Prepare a double boiler
Bring 1–2 inches (2.5–5 cm) of water to a gentle simmer in a saucepan, then place the bowl of chocolate above the water so it doesn’t touch the surface. Maintain low steam and avoid boiling; direct steam or water splashes will seize chocolate. Keep the heat at a low simmer to control temperature precisely.

Step 3: Melt chocolate to target high temperature
Stir continuously while melting until smooth. For dark chocolate, heat to 115–120°F (46–49°C); for milk or white chocolate, heat to 105–110°F (40–43°C). These higher temperatures fully melt all crystals so you can reset their structure with seeding.

Step 4: Remove from heat and cool slightly
Take the bowl off the double boiler and dry its bottom to prevent steam. Let the chocolate cool uncovered, stirring occasionally, until it reaches 88–90°F (31–32°C) for dark chocolate or 84–86°F (29–30°C) for milk and white. Cooling prepares the chocolate for effective seeding.

Step 5: Add tempered chocolate seeds
Chop or grate 10–20% of the total weight as tempered seed chocolate and stir it into the melted chocolate. For 12 ounces (340 g) melted, add about 1.2–2.4 ounces (35–70 g) of tempered chips. Stir constantly until the seeds fully melt and the temperature falls to working range.

Step 6: Bring to working temperature
Gently warm and stir to reach the final working temperature: 88–90°F (31–32°C) for dark chocolate, 84–86°F (29–30°C) for milk, and 82–84°F (28–29°C) for white. Use brief contact with the warm bowl or the double boiler; avoid exceeding the target or you’ll need to re-seed.

Step 7: Fill molds and set
Pour or pipe chocolate into clean, dry molds, tapping to release air bubbles and scraping excess for sharp edges. Let molds sit at room temperature (65–72°F / 18–22°C) until firm, about 20–40 minutes, or refrigerate 10–15 minutes for faster setting. Unmold by inverting and tapping once chilled and fully set for a shiny surface and crisp snap.

- Work in a cool, dry room below 72°F (22°C) and under 50% humidity to prevent bloom.
- Weigh chocolate and seeds for consistent seeding ratios—10–20% seed works well.
- If small streaks appear, re-temper by stirring in more seed chocolate rather than overheating.
- Use tempered chocolate pieces, chocolate couverture, or well-tempered bars as seeds—do not use candy melts.
- Polish molds with a soft cloth before filling to enhance shine.
- Keep water away from chocolate; even a drop can seize an entire batch.
- Do not let water or steam contact chocolate; this will seize and ruin tempering.
- Avoid overheating: exceeding the high temperatures by more than a few degrees can destroy temper and require restarting.
- If chocolate thickens and won’t melt with gentle heat, discard and start with a fresh batch to avoid poor texture.
- Refrigerating for too long can cause condensation when returning to room temperature—allow candies to come to room temperature in the fridge before unmolding if necessary.
