Why Temper Chocolate
If you’re going to temper chocolate it will be helpful to understand why it’s necessary and what it does to the chocolate.
Tempered chocolate is snappy, shinny and contracts away from the mould.
Chocolate is formed of six different crystalline structures and the one we need for snappy, shiny chocolate is the beta crystal. This is achieved by TTA (temperature, time, and agitation) we’ll come back to that in a moment.
When chocolate is not in temper, you have all the different crystals present. Which is why the chocolate will bloom, feel and look crumbly, have a ‘fudgey’ consistency, melt in your hand, and isn’t stable at room temperatures above 20-22c.
I think of the crystals as puzzle pieces. If you don’t take the time to assemble them correctly, the pieces don’t fit, the completed puzzle is not stable and will fall apart and it doesn’t look right.
The crystals in chocolate begin to separate at 33c-35c and completely separate when heated to above 45c, but no higher than 55c as the chocolate can burn.
From there, TTA comes into play. Now it’s time to agitate the chocolate, or keep it in motion, until it comes down to 26c-28c and then back up to 31c.
Mini – good for tempering small batches of chocolate or coloured cocoa butters
Large – good for tempering larger batches of chocolate, upwards of 300g or so
I use both very large, 10L capacity stainless steel bowls and smaller 3L mixing bowls when tempering and working with chocolate
The larger the bowl, the faster it tempers.
Personally, given the way I temper, I use a SS bowl lined with silicone as it stops the bowl from swirling around when I need to use the heat gun to heat it up.
Polycarbonate moulds or Professional moulds are the ones I use and my preferred brand is Chocolate World.
These moulds are made in Belgium and distributed worldwide.
Choose moulds that are plain in design when first starting out as they’re easier to learn with.
Avoid moulds with intricate designs or sharp turns and edges until you are confident in your skills.
Go for clear moulds, not white ones as you cannot see through them and they are notoriously more difficult to work with and attain a good temper with. Not sure why.
