You're not going to believe this, but your United States Department of Agriculture does not report on the sulfur content of any part of an egg. (And it's not just eggs! The USDA will tell you the amount of manganese or selenium in just about any food down to the third or fourth decimal point, but doesn't utter a peep about sulfur. Is it any surprise people wonder where their tax dollars go?)

There is great disagreement on the Web about your question. A prestigious academic site says sulfur in the yolk causes the greenish ring that sometimes forms around the yolk of an overheated hard-cooked egg, while the American Egg Board says it's sulfur in the white. The University of Nebraska at Lincoln (which we have never doubted) says sulfur in the white sometimes reacts with iron in the yolk.

Once again Ochef must step in to set the record straight. The USDA does not reference the sulfur content of foods because it is itself a component of several amino acids and vitamins, which the USDA does quantify. At least two of those amino acids - methionine and cystine - are present in both the yolk and white of the egg, so sulfur is also present in both parts.

We're thinking we might just get an honorary doctorate from those folks in Lincoln for our resolution of the great egg-sulfur debate. "Dr. Ochef" - has a nice ring to it, don't you think?
