I was mostly joking, but I did get some oily/greasy dust in my mouth, and it tasted kind of burnt and spicy, which is why I came up with “steak seasoning”

But yes, I do actually inadvertently get limestone in my mouth often, but unfortunately (or fortunately) it really doesn’t taste like anything. Maybe I will have to sample a larger size.

I might ask our geologist if she “taste tests” the rocks, according to what another commenter said…
