The defatting method pertains to a simple and practical removal of fat, oil or grease from a broth surface during cooking or right before eating, in order to consume broth without the floating oil, fat or grease for a better health. The embodiment of my method is to adopt a blower (28) generating air stream (22) and aiming at a specific area on the surface of broth (24) in a container (20), blowing out a certain area free or minimal of floating fat, oil or grease (26) on the broth surface. Then scoop out from this defatted area to extract broth (32) free or minimal of fat, oil or grease (26). Another embodiment of the defatting method is to tilt container (20) and level the liquid surface to the tip of the laid down side of container (20), divert forward air stream direction from the rear of container (20), continuously divert forward air stream direction to drive fat, oil or grease (26) until they completely overflow out of container (20), thereby leaving behind the fat free broth (24).
