The first time I saw this dish a few months ago in the program "my kitchen Rules". It's a cooking show, where 12 couples Amateurs compete for a prize. Well, not in this case. The dish is done in a large amount of oil, on low heat for several hours. That's how many times it was done, with different meats and even with vegetables, they say that the meat just melts with this technology. I was confused about the oil, but I finally broke down and made a rabbit. Painfully his meat dry. You know, I did not expect such a result. The meat just melts and butter is almost there. Much less than if done in batter.
