Tempering with Mycryo®

28 Mar

Tempering with Mycryo®

Step 1

Melt the chocolate at 40-45°C (in microwave or bain-marie).
Step 2

Allow the chocolate to cool at room temperature to 34°C for dark chocolate or 33°C for milk, white or coloured chocolate.
Step 3

Add 1% of cocoa butter Mycryo, or 10g for 1kg of chocolate.
Step 4

Mix well.
Step 5

When the chocolate is perfectly pre-crystallised, keep the temperature at 34°C for dark chocolate and at 33°C for milk chocolate and white.
Step 6

In order to use the chocolate over a longer period of time, keep it at 31-32°C for dark chocolate or 29-30°C for milk, white or coloured chocolate.

 

What is technically happening? 

Nothing more than a true tempering process. When you temper your chocolate on the marble or when you “seed” with more chocolate, you want to start a chain reaction to crystallize the Beta form of the cocoa butter contained in the chocolate. This specific crystallisation form will bring the shine and the snap you want to your chocolate. An ultimate tempering is crystallisation of only the Beta form of the 7 forms of crystals contains in cocoa butter. With this new technique of tempering, you are not creating Beta forms, you are simply…adding it. Indeed, 1% of Mycryo is just the right amount of Beta crystals to start the chain reaction. You then have the perfect crystallisation, leaving a longer time frame to work your chocolate, since you initiate the process from the very start.

Tempering with callets

Tempering with callets

Pre-crystallisation is very easy if you add chocolate which has already been tempered to the melted chocolate. Callebaut Callets are useful for this. Callets have of course already been tempered. In other words, they are already in the required crystalline form, and can be added to the melted chocolate. The required quantity of Callets depends upon the temperature of the melted chocolate and the Callets. When the melted chocolate reaches a temperature of approximately 40 °C, you can add 15% to 20% Callets at ambient temperature (between 15 and 20 °C).

 

 

Step 1

Melt the chocolate in a melting pan (set the thermostat to 45 °C).
Step 2

Lower the thermostat (± 32 °C for dark chocolate / ± 30 °C for white chocolate and milk chocolate) and immediately add 15% to 20% Callets at ambient temperature.

 

Step 3

Stir the chocolate well to ensure the dispersion of the stable crystals of the Callets. Are the Callets melting too quickly? That is because the chocolate is still too hot. Add more Callets and continue stirring.

Step 4 In this way, you will obtain a slightly thickened chocolate, which is ready to work with.

Mechanical tempering

Mechanical tempering

Step 1

Melt the chocolate in the tempering machine (setting the thermostat to 45 °C) then lower the thermostat (± 32 °C for dark chocolate / ± 30 °C for white and milk chocolate).
Step 2

Immediately add 15% to 20% Callets at ambient temperature.
Step 3

The machine mixes the Callets into the melted chocolate, dispersing the stable crystals throughout the already melted chocolate. Are the Callets melting too quickly? That is because the chocolate is still too hot. Add more Callets and continue stirring.
Step 4

That’s it! The chocolate has thickened, but has remained even. For tempering systems other than wheel-type machines, we recommend you contact your supplier.

Tempering in the microwave

28 Mar

Tempering in the microwave

Step 1

Pour some Callets into a plastic or glass bowl.
Step 2

Put the bowl into the microwave and melt the Callets at 800-1000 W.
Step 3

Take the Callets out of the microwave every 15 to 20 seconds and stir well to ensure that the temperature of the Callets is evenly distributed and that they do not scorch.

Step 4

Repeat this procedure until the chocolate has almost all melted. Some small pieces of Callet should still be visible in the bowl.
Step 5

Remove from the microwave and stir the chocolate well, until all the pieces of Callet have disappeared and a slightly thickened even liquid has been obtained: the chocolate is tempered and ready to work with.

Tempering on a cool (marble) work surface

27 Mar

Tempering on a cool (marble) work surface

Step 1

Melt the chocolate at a temperature between 40 and 45 °C in a double boiler or melting pan.
Step 2

Pour 2/3 of the melted chocolate onto the cool marble surface.
Step 3

Keep the chocolate moving by stirring continually with a spatula and a scraper.
Step 4

Continue to do so until the chocolate starts to thicken (when its temperature is 4 to 5 degrees lower than its working temperature): crystallisation takes place. You will see that ‘peaks’ are formed when the chocolate is allowed to fall from the spatula.

Step 5

Pour the pre-crystallised chocolate into the rest of the melted chocolate and stir until it forms an even mixture.

Step 6

The chocolate is now ready to work with. However, if the chocolate is too thick, reheat it until it becomes liquid again, but is still pre-crystallised. Take a sample: put the tip of a knife into the chocolate. If the chocolate is correctly tempered, it will harden evenly within 3 minutes at an ambient temperature of +/- 20 °C.

Tempering chocolate

Tempering Chocolate

All chocolate should be tempered before you use it to mould/pour, to use for creating blown figures, for coating cakes or pralines. In short, whenever chocolate needs to have a perfect sheen and be hard.
What is tempering? The purpose of tempering chocolate is to pre-crystallise the cocoa butter in the chocolate, which is related to the working temperature of the chocolate. During tempering, the cocoa butter in the chocolate changes into a stable crystalline form. It ensures the hardness, shrinking force and gloss of the finished product after it has cooled. If the chocolate is melted in the normal way (between 40 and 45 °C) then left to cool to working temperature, the finished product will not be glossy. If you make the effort of using a special way of bringing chocolate up to the right working temperature, you are guaranteed to get the desired end result. And that is what we mean by tempering: bringing chocolate up to the right working temperature so that there are sufficient stable crystals. The 3 factors which are important during tempering are time, temperature and movement.

Here are 5 way’s of tempering chocolate.
