One day I viewed a video from a native chef who cooks only the way her ancestors had reached her.

She uses a technique to dig an underground oven and bury her pots in the ground as the food cooks when the biochar is made.

I think that is a clue as to why they used so much biochar. It was their way to cook. But again hard to know.
