Tempering Chocolate

Hello again!

I think this blog is going to be more about technique than actual recipes, but hey, who cares, it's my blog. I want today to discuss what I promised yesterday. How and why to temper chocolate. First off, people think this is something hard and amazing and, really, it's not. It's time consuming and space stealing, but that's about it.

Tempering chocolate is moving chocolate around at a rapid pace until it takes on a thicker consistancy. The reason you do this is so that the crystals in the chocolate won't break up upon setting and you won't get a wobbly coloured piece of chocolate. Such as this:

Those spots are fat blooms. They are what happens when chocolate cools and the chocolate separates from the milk fats. It does not affect the taste of the chocolate whatsoever. However, it does affect the appearance. And as we know, appearances can be everything.

Now this may seem like a waste but I need you to melt your chocolate to around 43C and then throw the entire thing on a cool slab of marble. Any surface will work, really, but marble is much better as it retains it's temperature as you play with your chocolate for what should be around five to ten minutes, depending on amount.


Using a chocolate palette knife and, I'm not kidding here, a paint scraper, move the chocolate around, making sure it's not sticking to your surface. Now a paint scraper is not the actual clinical chocolate making tool here but it works JUST AS WELL. The only difference you'll find is a paint scraper may rust quicker. If you plan on working with chocolate for many many years, buying the proper tools is ideal... but for $3 at Bunnings, this will work just fine.

This process is a lot like kneading bread without hands. You want to move around the entire blob and mix it a well a possible. To test the chocolate, dip a small plastic spoon in it and let it dry. If it comes out warbled, it's not good. If it comes out smooth and shiny, it is good. If it comes out smooth and dull, it needs a tiny bit more work.

Now if you wish to keep using this chocolate for a few hours, keep at a steady temperature.

Dark : 32C
Milk : 30C
White : 29C

Now every 30-40 minutes when working with the chocolate test it again. If it comes out warbled it may only need a quick stir with a wooden spoon! If it starts to harden, instead of turning up the heat, apply a blowdryer to your chocolate to melt it back down. Test again.

Voila, tempered chocolate!

  2. This is really interesting. After you've 'kneaded' the chocolate where do you keep it to work with it or do you transfer it straight to an acetate sheet/moulds etc?

  3. As you can see from the last photo, the ideal place to store it is in a heated specifically designed chocolate melter. Since those things can be expensive, it can either be transfered directly to your project or placed on a low simmering ban-marie with a thermometre stuck in it for ideal and closely watched temperature. Of course since you're doing everything at home, you're unlikely to be dealing with mass quantaties of chocolate, so most likely won't have it lying around long enough to cool if you've decided on a project.
