I am not expert, but first google link says that simplest curing process is to brine it for 3 days in salted water and then bake, I don't think it will be counted as ultra-processed: https://www.homesicktexan.com/how-to-cure-ham/ https://www.homesicktexan.com/how-to-cure-ham/ But I think corps likely apply tons of chemicals to extend shelf life, make process faster and improve taste. From another hand, I had no idea what is the process until I just googled. And I buy many types of food, and don't have chance to do my research, so labeling would be superhelpful.
