Chocolate Tempering Guide

Why Temper Chocolate?

Chocolate contains cocoa butter, which forms six different crystal structures (polymorphs I-VI). Only Form V crystals produce: glossy surface, firm snap, smooth melt, good shelf life, clean release from moulds. Untempered chocolate: dull, streaky, greasy surface. Soft, no snap. Unstable — blooms (fat or sugar crystals migrate to surface). Tempering creates predominantly Form V crystals by controlled heating and cooling. Once the chocolate contains enough stable Form V seed crystals, further cool

Temperature Ranges by Type

Dark chocolate (70%+): melt to 50-55°C, cool to 27-28°C, work at 31-32°C. Dark chocolate (50-70%): melt to 50-55°C, cool to 27-28°C, work at 30-31°C. Milk chocolate: melt to 45-50°C, cool to 25-26°C, work at 28-30°C. White chocolate: melt to 40-45°C, cool to 24-25°C, work at 27-28°C. The working temperature is the most critical — this is where you have enough Form V crystals (set during the cooling phase) but the chocolate is still fluid enough to work with. Too hot: melts the seed crystals, nee

Seeding Method Step by Step

Seeding is the most accessible method for home use: chop or grate tempered chocolate for seeds (30-35% of total weight). Melt 65-70% of your chocolate to the melt temperature (use microwave at 50% power in 30-second bursts, or bain marie). Remove from heat. Add the seed chocolate (the finely chopped tempered chocolate) — it melts slowly while introducing Form V crystals. Stir continuously until the seed melts and the working temperature is reached. Test: dip a knife — set within 2-3 minutes at r

Troubleshooting

Fat bloom (grey or white streaks on surface): incorrect tempering temperature. Got too warm during working. Storage temperature fluctuated. Solution: re-melt and re-temper from scratch. Sugar bloom (rough, mottled surface): moisture got to the chocolate during setting. Cold moulds causing condensation. Setting in a humid environment. Solution: ensure moulds are at room temperature, set in a cool dry environment. Chocolate too thick to work with: temperature has dropped too low during working. Ca
