Add the vinegar (150 g/ml) to distilled water (275g/ml) and glycerol (7g/ml), then stir until boiling.
Add chitosan (10 g) to the mixture stepwise in small portions, whilst stirring until dissolved into solution. Reduce the heat of the solution whilst adding chitosan to a simmer (65-75 ºC), and stir until homogenous.
Dissolve the Chitosan, add the methylcellulose (10 g) stepwise and stir in solution. You may still find small lumps over time depending on the grade of chitosan - Remove these with a spatula.
Pour into moulds, once all the solids have dissolved. Then leave to set in the air - once moderately set transfer to the dehydrator at 35 ºC for 18-21hrs.
