There is provided a processed egg capable of making a puffed egg product which has good restorability when restored with hot water, and a method for identifying such processed egg. [Means for solution] The processed egg is characterized by having a slope of 20 cP/min or more in viscosity measurement using a rapid visco-analyzer (RVA). The method for identifying a processed egg suitable to be puffed comprises mixing a processed egg and water, measuring viscosity of a mixture of the foregoing step using a rapid visco- analyzer (RVA), and calculating a slope in viscosity change based on a measurement result obtained from the foregoing step [Selected Figure] Fig. 1
