Marion Harris Neil, The Story of Crisco
“ Cooking in stoneware has no equal where slow cooking is aimed at, and there are many dishes which one would do well to refrain from attempting unless cooked in this fashion. These cooking pots are inexpensive, and certain foods taste decidedly better if cooked in this way. For braising, pot roasting, or stewing fruit and other articles which need to be cooked slowly under close cover, the application of a moderate, even heat produces far better results than if quick heat is applied. For such cases the use of earthenware cooking pots is recommended. ”
