Step one

Mix all the ingredients in a small pot

Step two

Heat at a medium temperature, stirring continuously

Step three

Mix until there are no clumps. Then heat the mixture to 95C or to when the solution starts to froth (whichever comes first). Once it reaches this point, remove from the heat and continue to stir. 

Step four

Scoop out any excess froth with a spoon or strainer. Pour the mixture into a flat tray mold and allow it to dry out. 

Step five

The amount of time it takes the material to dry strongly depends on the thickness of the final product as well as the temperature and humidity in the room. It might take several hours until the sheet has fully dried. Once it is ready the sheet can be removed from the mold.
