Texture matters more in cooking than I think a lot of folks give it credit for.
Think of a BLT. While it has bacon, it's not just any bacon: It's crispy bacon.
The sandwich works almost entirely on the basis of the textures of the ingredients: The crunch of the lightly toasted white bread, the wetness of the smear of mayo, the crunch of the crispy bacon, the wetness and give of the tomato, the crunch of the iceberg lettuce and then, again, the toasted bread.
Although the saltiness of the bacon stands out, when I think about a good BLT (which I do, more often than I'd like to admit), it's all about that texture.
So I stand by "pleasing grit" with pizza cornmeal.
