Sandra Lee makes it to the big time on The Food Network by taking packaged food items and adding this or that to them to make it to suit her style. Ah hem... I've been doing that long before Sandra Lee became a millionaire by tweaking a box of cake mix and other works. Haven't you made a little change here or there and made it to suit your own tastes?
Here's one I tweak, and I don't make it the same way each time, either. I chose Pound Cake because to make a Pound Cake from scratch requires more eggs than I want to use.
