How to Temper White Chocolate: Temperatures, Seeding and Machines

Short answer: to temper white chocolate, melt it completely at 40–45°C (104–113°F), bring it down by seeding it with unmelted chocolate, and work it at about 28°C (82°F). That is lower than dark chocolate, which Le Cordon Bleu works at 32°C (90°F). The figures below come from Le Cordon Bleu, Martellato's Meltinchoc manual, pastry professor Peter Greweling and chocolatier Ewald Notter; the curve printed on your own white chocolate's bag or technical sheet always comes first.

White chocolate tempering temperatures

White chocolate is melted, cooled and worked at lower temperatures than milk and dark chocolate. This is the curve Le Cordon Bleu teaches for each type:

Chocolate	Melt to	Cool to	Rewarm and work at
White	40°C (104°F)	25°C (77°F)	28°C (82°F)
Milk	45°C (113°F)	26°C (79°F)	29°C (84°F)
Dark	45°C (113°F)	27°C (81°F)	32°C (90°F)

Other professional references give similar figures:

• Martellato programs its digital Meltinchoc melters to melt all three types at 45°C (113°F) and, after seeding, to hold white chocolate at 28°C (82°F), milk at 29°C (84°F) and dark at 31°C (88°F).
• Peter Greweling (Culinary Institute of America) puts the optimum working temperature of milk and white chocolate very close to 30°C (87°F), and of dark chocolate very close to 32°C (90°F).
• Ewald Notter (The Art of the Chocolatier) melts white and milk chocolate at 43.3–46.1°C (110–115°F), and dark chocolate at 46.1–48.8°C (115–120°F).

Every white chocolate has its own recipe, so the curve on its bag or technical sheet is the one to follow. If it has none, start at 28°C (82°F) and confirm with the temper test further down.

Why white chocolate needs its own curve

White chocolate is built differently from dark: it has no cocoa liquor. Its main ingredient is sugar, followed by cocoa butter and milk powder (BCcampus, Understanding Ingredients for the Canadian Baker). All the sources above temper it lower than dark chocolate, so a dark-chocolate curve is the wrong starting point.

Check one more thing before you start: is it real white chocolate or a coating? In Canada, cocoa butter must be the only fat in chocolate; a product made with vegetable fats or oils cannot legally be called chocolate and has to use another name, such as "candy". Compound coatings replace the cocoa butter with a hard fat, usually hydrogenated palm kernel oil, so they do not need tempering. BCcampus gives about 40°C (104°F) as the best coating temperature for compound chocolate, and warns that heating it to 50°C (122°F) or more can destroy its seed crystals.

Method 1: seeding, the easiest way by hand

Seeding cools melted chocolate with chocolate that is already crystallised, so the stable crystals are carried into the batch. Greweling explains that tempering pre-crystallises a small quantity of the cocoa butter, about 1%; those crystals become seeds that make the rest set quickly and evenly. Notter adds that gentle stirring helps the seed crystals multiply.

Le Cordon Bleu's method, with its white chocolate temperatures:

1. Chop the white chocolate finely and set one third aside.
2. Melt the other two thirds over a bain-marie to 40°C (104°F), checking with a thermometer.
3. Take the bowl off the heat and stir in the chocolate you set aside.
4. Keep stirring until the chocolate cools to 25°C (77°F).
5. Put the bowl back over the bain-marie and warm it gently to 28°C (82°F). Work at that temperature.

A probe thermometer makes each step measurable; an infrared thermometer reads the surface without touching the chocolate.

Method 2: tabling on marble

Tabling cools part of the melted chocolate on a stone slab, then mixes it back into the rest. Notter describes it as the fastest and most efficient way to temper small amounts, because the stone draws heat out of the chocolate without getting very hot itself, but it takes more hand-eye coordination than seeding.

• Work quickly and cleanly, and keep your spatulas free of excess chocolate to avoid lumps (Notter).
• Tabling time depends on the amount of chocolate and on the temperature of the room and the slab (Notter).
• If the chocolate gets too cold, reheat it and start again (Notter).
• Aim for the same working temperature as with seeding: about 28°C (82°F) for white chocolate.

Method 3: a digital melter or a tempering machine

A machine holds white chocolate at its working temperature for as long as you work, which is where hand methods lose time and consistency.

Martellato Meltinchoc Digital: white program at 28°C

Martellato's manual describes the sequence: select the white program; the display and a sound signal remind you to stir every 10 minutes; at 45°C (113°F) a symbol tells you to seed by adding more chocolate; press Set and the melter brings the chocolate down to 28°C (82°F) and keeps it there. Martellato recommends stirring during use. The MCD101 holds 3.6 L and the MCD102 6 L; both run on 110V with PID control and an integrated probe, and include a 145 mm scraper.

Pavoni Italia MiniTemper: your own white curve, saved

The MiniTemper tempers in three stages (melt, crystallise, harden) and saves five programmable presets, so the curve on your white chocolate's sheet can be stored once and recalled with a button. Its 3.5 kg tank has an interchangeable basin for switching between chocolate types, the temperature is set from 20 to 60°C (68–140°F) in 0.5°C steps, and it runs on 110V. A spare bowl lets you keep one basin for white chocolate.

How to check that white chocolate is tempered

Dip the tip of a palette knife in the chocolate and let it set at room temperature. Greweling's test: dark chocolate should set within about seven minutes, free of streaks or a grainy texture; milk and white chocolate take a little longer.

• Streaks or a grainy texture: Greweling attributes any problem in the temper test to underseeding. Do not warm the chocolate; create more seed by adding more chocolate, or table a bit more.
• Too cold while tabling: reheat and start again (Notter).
• Grey or white marks days later: see the 8 most common tempering problems.

Why the seed crystals matter is explained in our guide to chocolate crystallization.

How AI can help your production

Give an AI assistant the curve from your white chocolate's technical sheet and ask it to write a one-page tempering procedure for each method you use, with a line to record the melt, cool and working temperatures and the temper-test result at every batch. Ask it to scale the seeding quantities to your batch sizes and to turn the log into a weekly summary, so you can see which shifts or batches fail the test and why. A written routine keeps everyone tempering white chocolate the same way.

AI organises the information; tasting and the final decision stay with your chef.
