I was culling my recipe files and I came across this recipe I had downloaded in 2003. I haven't tried the recipe yet which explains the need to cull my files. I was looking for a color picture to go with the recipe and I couldn't find this version anywhere. So I'm entering this recipe in case anyone would like to try it.
