Good question. Maybe not cook, but consider someone who picked just the right ingredients and preparation for a sandwich. Combining flavors and textures in novel ways that are as surprising as they are delicious. I would ascribe more of the creative credit to that person vs. the one cutting the bread.
So you are taking the ridiculousness of calling someone a 'sandwich artisen' (slapping together assembly line type products is slapping together assembly line type products) but trying to spin it into a positive label?
