Portion drift: what ten grams costs

One dish. A few grams over the spec on every plate. Move the sliders. Illustrative; every figure is yours to set.

Cost of the component you over-serve, per 100 g£2.80 Grams over the spec, per plate10 g Plates a week70

The example starts at smoked salmon: £14 for 500 g, so £2.80 per 100 g, ten grams over on 70 plates a week.

Per plate£0.28

Per week£19.60

Per year, one dish£1,019

The Plate check tab in Recipe Spec Sheets does this from your own weigh-ins: three plates, three times a week, drift priced against the card's target weight. Not advice; a method.
