The "white" appearance sometimes noted when cake chocolate has been kept in stock for a long time is not attributable to age—it probably indicates that it has at some time been exposed to excessive heat. When pure chocolate is subjected to a tem perature of 96 degrees or thereabouts, it begins to melt and allows part of the oil or butter to rise to the surface. When the temperature is lowered, so that the choco late again becomes solid, the outside of the cocoa will show a thin covering of congealed cocoa-butter, which being of a yellowish color looks "white" in contrast to the brown of the chocolate itself. It is also erroneous to suppose that this is an indication that the chocolate is of inferior quality or is injured for practical use, for if it should be melted again and poured into molds and cooled at the right tem perature it would resume its original color.
