White chocolate requires lower temperatures and closer monitoring. Melt 335g to 110°F (never exceed — proteins will burn), seed with 165g, cool to 78°F, and reheat gently to 82–84°F.
Tempering involves three temperature stages: melting, cooling (crystallization), and working. Dark chocolate melts to 120–130°F, cools to 82°F, then reheats to 88–90°F. Milk and white chocolate use lower temperatures (105–115°F melt) because milk proteins and sugars are heat-sensitive.
| Chocolate | Melt (°F) | Cool (°F) | Work (°F) |
|---|---|---|---|
| Dark (55–70%) | 120 | 82 | 88–90 |
| Milk (30–45%) | 115 | 80 | 86–88 |
| White | 110 | 78 | 82–84 |
| Ruby | 105 | 79 | 82–84 |
The seed method involves melting 2/3 of your chocolate to full temperature, then adding finely chopped already-tempered chocolate (the "seed") to introduce stable cocoa butter crystals. The seed chocolate lowers the temperature while providing a crystallization template.
Properly tempered chocolate sets within 3–5 minutes at room temperature (65–70°F) with a glossy, smooth surface. It should snap cleanly when broken and not show white streaks (fat bloom) or gray spots (sugar bloom). Test by spreading a thin layer on parchment — it should contract and release from molds easily.
Once at working temperature, tempered chocolate stays workable for 15–30 minutes depending on room temperature and batch size. Larger batches retain heat longer. If it thickens or cools below working temp, gently rewarm in 5-second microwave bursts.
