Egg White is also very good. My mother poured boiling gravey on Thanksgiving once over her hand and we cracked open an egg, carefully covered her hand with the egg white and blew on it to help it dry, and while it was sore, where the egg white covered her hand, it was only red, but in a spot we missed, a blister developed. it also helps the pain once the air is sealed away from the burn for some reason. but I do like the flour idea, I think it is quicker than egg white and will keep it in mind. thanks.
