Fancy Pants Techniques - Part 2

Welcome to Part 2 of the dessert techniques series! Today I will be covering a technique that is bound to impress: tempering chocolate. If you've cooked with chocolate before, you may have noticed that once you have cooked with it, it can become dull, soft, and even have a white "bloom" sort of appearance on the surface. This happens because when in a solid form, the cocoa butter crystals in the chocolate are suspended. However when it is heated, this suspension is broken and the crystals surface, causing the "bloom" appearance when it is cooled. So whilst it still tastes nice, it doesn't look the best!
The idea of tempering the chocolate is to return the chocolate to it's suspended state and ensure that when you use it, e.g. for chocolate moulds or cake decorating, it maintains that glossy finish and crisp snap. Here's the how-to:

How to Temper Chocolate

What you will need:

• Required chocolate for your recipe
• A cooking thermometer
• A saucepan of simmering water 
• A bowl that sits on top of your saucepan but not fully in it 
• A spatula or spoon

Method:

1. Chop the chocolate in to pieces of the same size, as small as you can get them. Alternatively, you can roughly chop the chocolate and blitz it in a food processor in order to ensure uniformity.
2. Place 2/3 of the chocolate in the bowl and sit it in the saucepan over the top if the water, but not touching it (as contact with the water will make your chocolate too hot and the elements will separate).
3. Melt the chocolate to 50 degrees Celsius, stirring occasionally.
4. Remove the chocolate from the heat and add the remaining 1/3 of chocolate, stirring until the chocolate is consistent and reaches 32 degrees Celsius.

Test: spread your chocolate in a thin layer on to a plate. If it sets quickly and has a shiny, smooth finish, you have successfully tempered your chocolate!
