I'm an onion eater from way back, and vidalias are without doubt the best I have ever had. I guess everyone knows this, but just in case, the three ot four counties in Georgia where Videlia onions are grown, (a trade marked brand, ) has the lowest sulfur content in the soil, of any place in the country! We have been buying really good onions at Sams the last couple of years, in the winter months, when we can't get vidalias, that are grown in Geogia, but not labeled with trhe trade mark, Vidalia! They are not quite as good as vidalia, but close!
