In my original adobo for al pastor I added pineapple. Most times the pineapple was fresh, but I decided to eliminate that in my revised recipe above. I still use pineapple grilled or to cook along with the pork, depending on the recipe. As you will read in some of the other al pastor post, the fresh pineapple caused the pork meat to break down too much! The texture is not pleasing, lol! That's all I have to say! Trial and error! That's how we learn.
