I don't know if this was the intent. But to me it seems like a progressional
option. When a player first starts, they have basic unlearned cooking but
survivable, meaning charred that drains water. They progress to the grilled
that is the same as the charred except it does not drain water.
It is simple and nomadic in nature, all you need is a pot and grill, and can make sustainable
food, anywhere. 10x10 equals 100 so a single stack can cover a beginner for a full
days activities. So it does fit, because in the beginning, everyone needs to be somewhat
mobile in order to become established, meaning gaining xp to achieve points, to place
in perks, to gain multi ingredient recipes. And instead of it becoming useless it was re-purposed
as a base ingredient. At least that's how I started using it.
