egg‐white The white of an egg is in three layers: an outer layer of thin white, a layer of thick white, richer in ovomucin, and an inner layer of thin white surrounding the yolk. The ratio of thick to thin white varies, depending on the individual hen. A higher proportion of thick white is desirable for frying and poaching, since it helps the egg to coagulate into a small firm mass instead of spreading; thin white produces a larger volume of froth when beaten than does thick.
