No, pork was considered spiritually unclean. Where in the Bible, or the Torah, does it say that it can be made spiritually clean by cooking? God said don't eat it so you don't eat it.
To me, the Bible is a God given manual for our lives. Not all things are spelled out. In fact, we must search it to try and understand what God is saying to us.
I would say that people had died from eating pork. Therefore, it was clearly noted not to eat of it.
I am not a scholar. I just know that there are reasons for all of God’s Word. We are to use it to safety walk through this treacherous world.
