I used to make liver cake - it stunk the house out; worse than cooking liver on its own but they love it.

Also sardine/pilchard cake is deliciously stinky and they go nuts for it

TBH though, it's easier to just cook some liver slowly in the oven, with some garlic granules sprinkled over it. Cut it up into tiny bits when it's cool. Liver cake IS good, but a) It's disgusting to make (and it blew up my food mixer), and b) It makes your house stink.
