Mangalitsas are originally from Hungary, but about 60,000 of them can now be found across the world, including the US. They take about one year -- twice the time of other breeds -- to grow into a full-bellied, 300+ pound sheep-pig, but it's well worth it. Why? The Mangalitsa's meat is a melt-in-your-mouth 50% fat, probably making for the world's greatest bacon.
