Restaurant food cost: compare recipes with what the kitchen used

The kitchen's food cost increased, but the supplier's prices barely changed. Before changing menu prices, compare what the recipes say should have been used with what the stock records show was consumed. The difference can come from portioning, preparation yield, spoilage, unrecorded meals, or a simple count error. Those causes need different responses.

Choose the same period, locations, and ingredients for both sides of the comparison. A Sunday closing count compared with sales through Monday creates a variance before anyone has wasted food. Record the count time and treatment of deliveries, transfers, and prepared items that were present at that moment.

Multiply menu items sold by the ingredients and quantities in the applicable recipe. Include modifiers that change material usage, such as an extra protein portion or a substituted side. A menu mapping that omits modifiers can make correct kitchen work appear excessive. Retain recipe versions when portion size or ingredients change.

Toast's actual-versus-theoretical documentation ties theoretical consumption to menu sales and mapped recipes. Its recipe guidance also separates preparation batches from finished menu items and includes yield information. Use those distinctions to represent what the kitchen actually produces, even if the calculation lives outside that software.

A case, kilogram, trimmed kilogram, and portion are different measures. Record the pack size and the conversion into the recipe unit. If trimming or cooking changes usable output, identify where that yield is represented. Including an allowance in the recipe and then adding the same expected loss again in a variance explanation double-counts it.

Prepared sauces and proteins need attention at the count. Count their remaining usable quantity and use a documented recipe cost. Otherwise, ingredients already converted into prep can disappear from raw stock while the finished preparation is left out of closing inventory, overstating consumption for the period.

Start with opening inventory, add receipts and transfers in, then subtract closing inventory and transfers out. Treat documented returns and other movements consistently. This is a physical consumption bridge; the accounting valuation still follows the business's approved cost policy. Keep price changes separate from quantity differences where possible.

In a hypothetical example, a restaurant starts with 120 kilograms of an ingredient, receives 80, and ends with 50, with no other movements. Actual consumption is 150 kilograms. If 600 recorded dishes each require 0.2 kilograms on the same measurement basis, theoretical consumption is 120 kilograms. The 30-kilogram difference needs explanation.

At an illustrative constant cost of $5 per kilogram, that quantity gap represents $150. It is not proof of theft or careless portioning. Check counts, mapping, yield, and non-sale usage before assigning a cause. A negative variance can also result from missing purchases or an overstated count; favorable arithmetic does not guarantee reliable records.

Separate staff meals, complimentary dishes, tastings, spoilage, preparation mistakes, and customer remakes where the records support them. A manager-approved meal is a different business choice from product that expired unnoticed. Both use ingredients, but only a clear reason code makes the review actionable.

Keep the original actual consumption visible after adding explanations. A waste log should explain part of the gap, not remove the food from the calculation. If a report deducts logged waste to show an unexplained remainder, label both the total variance and the remainder so readers understand what changed.

Start with ingredients that have material cost or repeated unexplained differences. The next action might be correcting a pack conversion, checking a prep yield, changing purchase quantities, or reviewing a specific service period. Avoid imposing a blanket portion reduction when the evidence points to a data problem.

Retain the calculation and the change made, then compare a later period with a similar menu and operating pattern. When presenting food cost as a percentage of sales, define the sales denominator and treatment of discounts, taxes, and non-food revenue. A useful food-cost review explains both the ingredient movement and the commercial context of the meals sold.
