We have found only a few people who cook the head whole.
One reason is that leaving it whole makes it harder to soak the blood out. Bill Lamb gave a different reason, saying, "Henry'd killed a hog, and when he come in from work, they had it sittin' there cooked. Hadn't even cut th' ears out, th' eyes’r nothin'. Just cooked th' whole head like it was. Had it sittin' in a dish. That'uz th' first thing he seed was that hog lookin' at him when he come in t'dinner, an’ he just turned and went back an' never eat a bite."
