One by-product of making oil is a solid cake from the residue of the seeds. This can be fed to cattle, composted or burnt on a fire to provide roaring heat.
For burning, this cake is formed into briquettes. Simply add these to an already hot fire and allow it catch.
Each briquette will burn for around 30 minutes and remain hot for up to an additional 45.
These briquettes are also available at Baydon Stores, Packaging Not Included (Marlborough) and Planks Farm Shop (Devizes)
