I have been trying to do a recipee i saw on a site for trout. It suggest's getting 4 trout already gutted and liquidizing them and putting gellatine to make it solid and freezing it all to give to the Garters. Never again. I did it with 2 Trout and i am glad i only got 2 in the end. Cutting them into small chunks and liquidizing them. What a mess. Done it and waiting to see how it turns out.

Costs
1 Liquidizer £7.90
1 Packet of gellatine £0.63p
2 Gutted and beheaded trout £2.83

Hope it works.
