Tempering Chocolate — Seed Method (10% Seed by Weight)

90%

Melted chocolate (untempered) — Fully melted and held above the seeding temperature to destroy all crystal forms

10%

Tempered chocolate seed — Finely chopped callets, pistoles, or grated block; must already be in temper (glossy, snaps cleanly)

1. Melt the base chocolate completely to the 'destroy' temperature (dark: 50–55 °C / 122–131 °F; milk: 45–50 °C / 113–122 °F; white: 40–45 °C / 104–113 °F) to ensure all cocoa butter polymorphs are dissolved. 2. Allow to cool to the 'seeding' temperature (dark: 34–35 °C / 93–95 °F; milk: 33–34 °C / 91–93 °F; white: 31–32 °C / 88–90 °F). 3. Add the seed (10% by weight of the total batch), stirring steadily in a figure-eight or circular motion until fully incorporated and the seed pieces vanish. 4. Continue stirring until the mass reaches the 'working' temperature (dark: 31–32 °C / 88–90 °F; milk: 29–30 °C / 84–86 °F; white: 27–28 °C / 81–82 °F). 5. Perform a set test: spread a small amount on parchment; properly tempered chocolate sets with a gloss within 3–5 minutes at room temperature. 6. Use immediately for dipping, moulding, or enrobing.

• Temperature accuracy is everything — invest in a digital probe or IR thermometer calibrated to ±0.5 °C; guessing by touch is not reliable
• The seed must be properly tempered chocolate — using bloom-covered, old, or poorly stored seed introduces unstable crystals and defeats the method
• Stir continuously once the seed goes in — standing pools develop hot spots that melt out the crystals you are trying to propagate
• Dark chocolate has the widest working window (31–32 °C); milk and white chocolate are far less forgiving — a degree too warm and temper breaks instantly
• If the chocolate thickens too much (over-crystallized), reheat very briefly to 32 °C for dark, 30 °C for milk — do not exceed working temperature
• Chocolate bloom after setting indicates poor temper: grey-white fat bloom (cocoa butter migrating to surface) or white sugar bloom (moisture condensation recrystallizing sugar)

• Callet/pistole seeding

  Callebaut and Valrhona both produce couverture in pre-tempered chip form — these are the ideal seed; add at 20–30% for faster seeding if working with a large batch

• Microwave seed method

  Melt 90% of the chocolate in 30-second bursts to 50 °C, then stir in remaining 10% callets at room temperature; lower-tech but identical chemistry

• Immersion blender seed method

  Commercial adaptation: pour seed into the bowl and use an immersion blender to rapidly incorporate and cool — faster but noisier

• Over-seeding (20–30%)

  Used when rapid re-tempering is needed in a warm kitchen; excess seed crystals are melted out as the temperature rises, leaving only Form V

• Caramel — Dry Method

  Another heat-and-cool transformation relying on precise temperature control to achieve a target crystal state

• Ganache (chocolate to cream ratio)

  Ganache centers require tempered couverture shells; seed method is standard for enrobing truffles

• Pâte à glacer ratio

  Compound coating that does not require tempering — the alternative when seeding is impractical
