Chocolate Refrigeration
Posted in: Geek Gear - Cool Tools (Read-Only)
@Clay What would you recommend as an ideal cooling time, assuming a temperature of around 55F?
Bearing in mind our coolers are not humidity controlled.
Is there an ideal chocolate temperature that the bars should reach before removal from the fridge for packing?
There is no simple answer because I don't know what kind of molds you are using (thermoform has different heat transfer characteristics than polycarbonate), the dimensions of the mold cavity (the thicker the bar the longer it takes), the temperature of the chocolate (it will take longer if the temper point is 32C compared with 30C), and the amount of airflow in the cabinet (how efficiently are you removing the latent heat of crystallization - which can be affected by what the molds are resting on).
I don't know about the temperature the bar has to reach (outside? how do you measure the internal temperature?) but there are some important clues: what does the surface look like and what is the snap? A soft snap is an important clue that the bar is not yet fully crystallized.
All that said, in a 55F cabinet with chocolate at a 30-32C temper point (86-90F) in a polycarbonate mold with good airflow top and bottom - you are looking at 12-15 minutes minimum.
