I used to tip it into my old bottling bucket at the edge of the garden with the tap open to dry out before throwing it all in the bin. I was instructed by SWMBO to stop doing this when the dog found it and ate his fill then spent the next two days crapping foul smelling flapjacks all over my lawn!
Now I stick it in the composter and shout at the dog any time he goes near it.
