Mix all the ingredients very well and until there are no lumps.
Pour the mixture into 2 x 250ml or 1 x 600 ml Glass Beaker and cover it with Heavy Duty Foil. Wrap the foil tightly over the beaker as it acts as a splash cover.
Place the Glass Beaker/s in a Pressure Cooker and get it to operating temperature and pressure. From this point, cook for 45 minutes.
Allow the pressure to release, then remove the Glass Beaker/s from the Pressure Cooker and wait for the temperature of the mixture to drop to 45°C.
In a glove box, pour the mixture into the Petri Dishes, then allow the mixture to cool.
Once cooled seal the Nutrient Plate with Parafilm. Watch the video : How to seal a petri dish-> www.mushroomguru.co.za/videos9817.html
