Thank you misty. Interesting cooking method that, soaking in petrol for a week then setting alight to it. That would make it more than burnt it would be cremated along the lines of a real cremation. I see he says "burnt until only a residue remains". Presumably ash.
As he was clear about cooked meat I believe he considers a slightly overdone pork chop as something that Eddie would not alert to.
Pork chops, with very little decomposition, fit for human consumption & subsequently cooked should not produce a cadaver dog alert although it is unclear whether Eddie had to be trained not to alert to same in the manner he was trained to not alert to roadkill. Cadaver dogs are known to alert to animal bones. They also do alert to cremains, which potentially misled the investigation into the disappearance of Deorr Kunz Jr.
IMO it's really important to bear in mind that Grime is a dog behavioural specialist, not a forensic scientist with detailed knowledge & understanding of the chemical compounds which make a dog alert.
