One price lives in one place. Change a pack price and every sub-recipe and plate that uses it moves, including the ones nobody would think to reprice. Cups and lids are ingredients too, so a cafe drink's cost carries its cup.

Menu engineering compares like with like, within a location and menu group, so a beer is never ranked against a steak. It sorts items into stars, plowhorses, puzzles and dogs, then asks questions rather than giving verdicts. The workbook ships no benchmark: your target, your yields and your prices are yours.
