What Is Tempering Chocolate?

If you've ever melted chocolate and let it set only to find it dull, streaky, or soft, you've experienced untempered chocolate. Tempering is the process of carefully melting and cooling chocolate to stabilise its cocoa butter crystals, resulting in a glossy finish, a satisfying snap, and a smooth melt on the tongue.

Tempered chocolate is essential for making chocolate bars, dipped truffles, bonbons, and chocolate decorations that look and feel professional. It sounds technical, but with a thermometer and a little patience, it's absolutely achievable at home.

Why Does Chocolate Need to Be Tempered?

Cocoa butter can solidify into six different crystal structures (called polymorphs). Only one of them — Form V — gives chocolate the desirable gloss and snap. Tempering guides the cocoa butter to form predominantly this stable crystal structure by controlling temperature precisely throughout the melting and cooling process.

Method 1: Tabling Method (Traditional)

This is the method used by professional chocolatiers. It involves pouring two-thirds of the melted chocolate onto a marble slab and working it with a palette knife and scraper until it cools to the correct temperature, then returning it to the bowl with the remaining warm chocolate.

  1. Melt chopped chocolate in a bowl over a bain-marie (hot water bath) to the melt temperature above.
  2. Pour two-thirds of the chocolate onto a clean marble or granite surface.
  3. Using a palette knife and scraper, spread, gather, and work the chocolate continuously until it cools to the "cool to" temperature above — it will thicken noticeably.
  4. Scrape it back into the bowl with the reserved warm chocolate and stir well.
  5. Check the temperature: it should now be at the "work at" temperature. Test on a piece of parchment — it should set within 2–3 minutes with a matte surface that quickly becomes glossy.

Method 2: Seeding Method (Easier for Home Use)

The seeding method is more accessible and less messy than tabling. It uses small pieces of already-tempered chocolate (the "seed") to introduce stable crystals into the melted chocolate.

  1. Finely chop your chocolate. Reserve one-third of it.
  2. Melt the remaining two-thirds over a bain-marie to the melt temperature.
  3. Remove from heat. Add the reserved chopped chocolate in small amounts, stirring constantly after each addition.
  4. Keep stirring until all the seed chocolate has melted and the chocolate has dropped to the "cool to" temperature.
  5. Gently warm it back to the "work at" temperature and test on parchment. If it sets glossy and firm within 3 minutes, you're in temper.

Common Tempering Mistakes

  • Any water contact: Even a single drop of water will cause chocolate to seize into a grainy paste. Keep everything completely dry.
  • Overheating: Heating above the melt temperature destroys all crystal structures and you'll need to start again.
  • Rushing the cooling: Don't put chocolate in the fridge to speed it up — this creates condensation and bloom.
  • Not testing: Always test a small amount on parchment before using your tempered chocolate on a project.

Uses for Tempered Chocolate

  • Dipping strawberries, truffles, and biscuits
  • Moulded chocolate bars and bonbons
  • Chocolate decorations (shards, curls, transfers)
  • Enrobing caramels and fudge pieces

Final Tip

Use the best quality chocolate you can find — ideally couverture chocolate, which has a higher cocoa butter content and is specifically designed for tempering and moulding. The better your ingredients, the better your results.
