Hi Greg, thanks for the explanation!
The original idea was that in order to make better food, we'd need to find salt veins.
But salt veins are unexpectedly rare on the server and food is slowly becoming annoying to make for everybody.
We voted to make Pam's salt craftable with the default recipe (water + pot), so we could use it to make better food, while keeping it separate from the salt veins spawning in the world. That way we can't just craft salt out of water and make sodium out of it (for instance).
The easy fix was to basically allow people to make salt, due to salt ores being too rare (keda is working on a way to retrogen the world with better ores), and make it stop unifying to GT salt and possibly un-oredictify it.
I guess we'll just wait for the harder fix, which is to wait for keda's rework on the veins.
