I had to find a way to separate the protein from the egg yellow. In one forum I encountered a quotation that delighted me:

How to Separate? Any cook will say that it is enough to transfer a raw egg from one half of the shell to the other several times and as a result, in one half will remain a pure yellow with cholesterol and in the understated cup - a protein with bird flu. Sugar for diabetes and white flour with nuts and chocolate for obesity You will add yourself, as salt for hypertension and strong coffee in a cup for ischemic heart disease. You will also throw off the scalp yourself so that osteoporosis will be harder with the years... ;)
