Final Recipes

I’ve researched & compiled all of the following recipes from a variety of sources with a huge debt to the APUG forum. They are not perfect & I certainly haven’t tested them in any rigorous scientific way. They are simply recipes that, after trial and error, have worked and importantly I’ve repeated them with success.
