Amything new I tried that I thought ahd a strong taste I put with other food she really loved first. So I personally did pureed meat mixed with her fav veg, like carrotts and courgettes.
I also read that if you cook the meat with veg in the first place it takes away the stronger meat taste a bit, to make it more palatable.
When you puree the meat add lots of water to it as it can be very dry.
We've had chicken, beef, trurkey, tuna, cod, prawns, plaice, haddock, mackerel. All to great success!
