Prep sheets that actually work

A prep sheet is not a recipe. It is the daily contract between what the menu promises and what the kitchen can actually produce. When it's right, a new cook can walk in on a Tuesday and hit the standard. When it's wrong, the chef is on the phone at four o'clock.

A working prep sheet has four things: pars by day-part (how many of each item we need for tonight's projected covers), a yield column (how much one batch produces), a prep quantity derived from par minus on-hand, and a column for the cook to initial when it's done.

The failure mode is a sheet that lists every item every day at the same quantity. That is a template, not a prep sheet. Pars should move with the forecast — a Wednesday needs a different prep than a Saturday, and a sunny bank holiday needs a different prep than a rainy one.

If your prep sheet hasn't been reviewed in the last quarter, the menu has drifted from it. Walk the sheet against the actual line at the start of a service and count the gaps. That walk is worth more than any consultant's spreadsheet.
