You care about the food????????????? I care about how the food performs and how much it costs. The plain grilled cheese costs little and has those slightly firmed up, grilled corners along with some support from the cheese. (It also carries no risk of sliding, popping, flying, or otherwise escaping
ingredients.) The corners fit neatly into the ketchup cups and, if necessary, the shopper can angle the sandwich so that ketchup drips down the long side of the bun. Shoppers who paint master the technique quickly. Others might need a little practice. Eventually, everyone can establish a proper ketchup-laden tool, a chain restaurant version of a makeshift paintbrush.
So now the useful food is on its way to the napkin. There, the handy sandwich records the necessary shop information in ketchup on napkin. (This is only for sleepy days when they shopper might forget twelve or nineteen details.) Now, this is not quite as evocative or elegant as quill on parchment. It is never, under any circumstances, to be compared with the exquisite calligraphy! But it gets the job done.
The technique works with fries. Some fries are more useful than others. Someday, I might try this with bacon.
What.
