A praline is a nut coated with crystallized sugar ultimately showing a bumpy or orange-peel surface. It is still a traditional know-how.
The core is a nut, generally a peanut or an almond.The coating dramatically increases the size of the nut.
The ingredient list used in the application is fairly short:
- Caster sugar
- Vegetable oil
How does it work?
First, a highly concentrated sugar syrup is prepared:
Pour a small quantity of water into a boiling pan
Add a large quantity of caster sugar to the pan
The relative proportion is 10/90;
Bring to a boiling point
Boil until the required sugar concentration is achieved but without burning
Keep the prepared syrup lightly boiling
The quantity is prepared to match a coating operation.
A coloured syrup is prepared separately in the same way but using a lighter sugar concentration.
The coating operation itself runs as follows. It is always a batch operation.
Pour the nuts in a rotating pan
Pour a ladle of sugar syrup onto the nuts
Wait for the syrup to disperse and quickly crystallize on the nuts
Repeat 2nd and 3rd operation until the desired size is achieved
Complete the coating with the addition of the coloured sugar syrup
The successive liquid and powder applications occur in a batch coating pan equipped with an air fan.
Syrup additions are usually made manually to keep the process flexible.
The limited quantities, the high concentration of the syrup, the final addition of colours which may differ make it difficult to mechanize the process.
Coating pan – traditionally made of copper now replaced by stainless steel.
How do you measure your success?
Key quality features
The product has typical features
It shows bumps but is evenly distributed. No cracks
Red is the standard. No white spots
Key quality parameters
The process displays critical factors to control
High concentration to quicken the crystalization
Timely addition of the syrup to build up the layer without burning
Ventilation to ensurethe drying of the sugar layer without generating dust
