Early in Huckleberry Finn, Huck complains about the food at the Widow Douglas's:
When you got to the table you couldn't go right to eating, but you had to wait for the widow to tuck down her head and grumble a little over the victuals, though there warn't really anything the matter with them. That is, nothing only everything was cooked by itself. In a barrel of odds and ends it is different; things get mixed up, and the juice kind of swaps around, and the things go better. 1
Twain's imagination was closer to Huck's barrel than to the Widow Douglas's separate pots. As he "mixed up" black voices with white ones, the flavors "swapped around" deliciously. America's taste in literature would never be the same.
