Spiced ham and Spam are both types of processed meat, but they differ in preparation and ingredients. Spiced ham is made from ground pork seasoned with spices and then cooked.  On the other hand, Spam is made from chopped pork shoulder meat combined with salt, water, and sodium nitrite.  While spiced ham has a more robust flavor due to the spices used in its preparation, Spam has a more subtle taste. Ultimately, the choice between spiced ham and Spam depends on personal preference.
