Chocolate Tempering Calculator

Look up precise tempering temperatures for any chocolate type and calculate seed amounts, working times, and batch sizes for flawless tempered chocolate.

Working Temperature

88°F

Melt To

122°F

Hold At

90°F

Time

~20 min

Dark Chocolate Temperature Curve

1. Melt to122°F
2. Cool to88°F
3. Hold at90°F

Too cool — reheat briefly

Seeding Method

Melt 11.7oz, then add 4.3oz of solid chocolate and stir until fully dissolved.

Process Time

Example Calculations

1Dark Chocolate Seed Method

Inputs

Chocolate TypeDark (70%)
Total Weight1 lb (454g)
MethodSeed

Result

Working Temperature88–90°F
Melt Temperature120°F
Cool Temperature82°F
Seed Amount150g (1/3 of total)
Working Time15–20 minutes

Melt 300g of dark chocolate to 120°F, then stir in 150g of finely chopped tempered chocolate. Keep stirring until the temperature drops to 82°F, then gently reheat to 88–90°F.

2White Chocolate Tempering

Inputs

Chocolate TypeWhite
Total Weight500g
MethodSeed

Result

Working Temperature82–84°F
Melt Temperature110°F
Cool Temperature78°F
Seed Amount165g (1/3 of total)
Working Time10–15 minutes

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.

Frequently Asked Questions

Q

What are the three temperatures for tempering chocolate?

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.

  • Dark: melt 120°F → cool 82°F → work 88–90°F
  • Milk: melt 115°F → cool 80°F → work 86–88°F
  • White: melt 110°F → cool 78°F → work 82–84°F
  • Ruby: melt 105°F → cool 79°F → work 82–84°F
  • All temperatures are for couverture chocolate (not compound)

Q

What is the seed method for tempering chocolate?

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.

  • Melt 2/3 of total chocolate to melting temperature
  • Add remaining 1/3 as finely chopped seed
  • Stir continuously until seed melts and temperature drops to cooling point
  • Gently reheat to working temperature if needed
  • Seed chocolate must be in good temper (shiny, snappy) to work
Q

How can you tell if chocolate is tempered correctly?

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.

  • Sets firm at room temperature in 3–5 minutes
  • Glossy, smooth surface with no dull patches
  • Clean snap when broken (not soft or crumbly)
  • No white streaks (fat bloom) or gray spots (sugar bloom)
  • Contracts slightly and releases easily from molds
Q

How long does tempered chocolate stay in temper?

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.

  • Small batch (< 1 lb): 10–15 minutes working time
  • Medium batch (1–3 lbs): 15–25 minutes working time
  • Large batch (3+ lbs): 20–30 minutes working time
  • Room temp above 75°F shortens working time (chocolate stays too fluid)
  • Room temp below 60°F causes premature setting
