Whether it's delicious or not is a personal opinion, just like some people like spicy food and some people don't, there is no way to say it's delicious or not.
So tell me why it is so expensive.
Because the pig in the toad in the cave is a special breed: Iberian black pig. This kind of pigs are free-range, and they are fed with natural acorns instead of feed, so the meat quality of pork is incomparable to other pigs. The yield is not high, but the feeding cost is high, and then the curing period is long.
The last process of authentic ham is hand cutting, and the labor cost is quite good. Generally speaking, it is expensive to sell.
