To temper chocolate is to heat, cool and heat chocolate again so as to stabilize the fat in chocolate and form stable crystals. These stable crystals are the ones that will make it firm and shiny in room temperature.There are several ways to temper chocolate. The traditional way (the most difficult and messiest!) is to tabler the chocolate – spread 2/3 of the melted chocolate on a marble surface until it reaches the cooling stage temperature and then add it back into the bowl. The easier way (and more practical at home) is to add ‘stable’ chocolate into the melted one. For example if you are working with white chocolate: Step 1 – First divide the amount you are going to work with into 2/3 and 1/3 portions. Step 2 – Take the 2/3 portion and melt it in a heatproof bowl over a bain-marie to 45C (113F). Step 3 – Remove the bowl from heat and add the remaining 1/3 of your chocolate into the bowl. Step 4 – Mix well until it cools to 27 C (81F) and the chocolate is smooth. If there are a few lumps, you can use the hairdryer to melt it in the next step. If there are a lot, it might be better to melt the whole batch again. Step 5 – Using a hair dryer, heat the sides of the bowl until the chocolate reaches 30C (86F). Actually a trick we learned at the pastry shop was to put the bowl directly over a stove for 5-10 seconds. This isn’t recommended if you are still studying in cooking school or you have a conservative employer/teacher! If you are tempering milk or dark chocolate, you need only adjust the temperature according to the table above. Although the process might sound or look daunting at first, it gets easier with practice. The good news is making chocolate at home can be done at your own pace. Even if you make mistakes or are messy, there will be no one shouting at you. Practice does make better and imagine what you can do with this later.
