I already knew this (did my research well for my Hungarian holiday) and ate it in Hungary. Extremely fatty meat. I prefer the fat. I rendered mine and made Schmalz with scratchings for spreading on bread.
Btw, also known as “Mangalitsa”. I think this is the Hungarian pronunciation.
Mangalica is a lot more expensive in Austria so I recommend checking it out at least once in Hungary. Even Austrians go to Hungary to buy Mangalica and goose products.
