pencil
Pencils have no nutritional value and are not intended for consumption.
About
A pencil is a writing instrument, not a culinary ingredient. Pencils consist of a wooden shaft (typically cedar or pine) surrounding a core of graphite, a form of carbon. The graphite core is responsible for making marks on paper and other surfaces. Pencils are manufactured items used for writing, drawing, and marking—not for consumption or use in food preparation.
Culinary Uses
Pencils have no culinary use. They are not edible, are not used in food preparation, and should never be ingested or come into contact with food intended for consumption. In a kitchen context, pencils may be used only for administrative purposes such as labeling storage containers, writing recipes, or recording inventory.
