Loretta I know I have read about her and I have a vague idea. Some people think she was a real person and some people think she never existed. There is alot of controversy.
I looked her up on Google and I followed your link.
Here is one statement I saw on a Google site
Sally Lunn, a French refugee, arrived in Bath in 1680 and established her bakery.
Who knows!! I saw where the recipes varied alot too. The ones on your link were really close to the one I have. The only really big differance was that recipe used 1 egg and mine uses 4 eggs.
I just know this recipe is really good!
