A recipe costing card is one page that shows what a single portion of a dish costs you to put on the plate. Every ingredient is on it, with a quantity and a price, and at the bottom there is a number you can hold up against the menu price. I have done this for dishes. The arithmetic is the easy part; the hard part is deciding what counts as an ingredient.

What goes on the card

One line per ingredient

The chapter on recipe and menu costing in a Penn State hospitality course (Chapter 7, Recipe and Menu Costing) describes the standard card as a list of every ingredient with its quantity, its unit, its cost per unit and an extension, which is the line cost, the quantity times the unit cost. The lines add up to a total for the recipe. The textbook’s seafood Newburg comes to $40.66 for ten portions.

The word “extension” is old restaurant bookkeeping, and it earns its place. A column that multiplies quantity by price keeps the two numbers visible side by side. When a cost looks wrong, you can see whether the quantity or the price is the culprit.

The unit has to match the price

If flour is priced by the fifty-pound bag and the recipe calls for cups, there is a conversion that somebody has to do once and write down. Do it on the card, in the open. A cost per unit that is secretly a cost per bag is how a dish ends up costing three times what the sheet says.

Everything that lands on the plate

The same chapter says the card should include accompaniments and garnishes, because the cost of a plate goes beyond the main recipe. It prices an herb garnish at $0.20 inside a $1.75 basic plate cost. For menus that change often, it describes a shared basic plate cost for the standard starch and vegetable, with the feature item added on top. That saves redoing the potatoes every time the fish changes.

I would add the things people treat as free: the bread basket, the pickle, the lemon wedge, the side of dressing. Each one is cheap. Together they are a cost nobody has written down.

Portions and what a portion costs

Divide the total by the portions

The standard portion cost in the textbook is the recipe total divided by the number of portions. The Newburg at $40.66 over ten portions is $4.07. The portion count is a decision, not a fact, and it should match what the kitchen actually puts on the plate. A card that says ten portions for a pan that the line portions into eight is a card that is lying with great precision.

The chapter gives a second way to the same figure for things bought in containers: the unit cost divided by the portions in the unit. Eggs at $2.00 a dozen with two eggs in a portion make six portions a dozen, and each portion costs $0.33. Those are the book’s numbers, and the point is the method rather than the price of eggs.

Then compare it to the menu price

Food cost percentage in the text is the portion cost divided by the selling price. The Newburg’s $4.07 against a $12.99 price comes out at 31.3 percent. That ratio is what tells you whether the dish earns its place. It is also only one number about one dish. A card does not know about your rent, your payroll or the fact that the dish sells forty times a night, and it should not pretend to.

As purchased and edible portion

You pay for the trim

This is the part that breaks home arithmetic. The textbook separates as purchased, the weight or cost when you buy it, from edible portion, what is left after trimming, peeling or cooking. Subtract the waste from the purchased weight and you have the edible weight. Divide edible by purchased and multiply by 100 and you have the yield percentage. The example in the text is a 2.5 kg beef tenderloin that trims down to 1.75 kg, a 70 percent yield.

The waste has a price. The text says it must be built into menu prices unless it is put to use, with bones going into stock as its example. A card that prices the tenderloin at the invoice cost per pound is pricing meat nobody serves.

The correction is one division

Edible portion cost is the as-purchased cost divided by the yield as a decimal. A culinary math text from Open Washington works two examples. Strawberries at $3.49 a pound with an 87 percent yield come to about $4.01 a pound for the part you use. Broccoli at $1.48 a pound with a 61 percent yield comes to about $2.43. The Penn State chapter does the same sum another way, with a factor of 100 divided by the yield percentage, and a whole turkey at $0.99 a pound with a 36 percent yield lands near $2.75 a pound.

Where do the yield percentages come from? The Open Washington text has you look them up in a table of yields from the previous chapter, which is fine for a first pass. The better source is your own kitchen. Penn State describes a yield test for meat and fish: weigh the item as purchased, weigh it after breaking it down, weigh it again after cooking, and record the values. From those weights you get a cost per usable kilogram and a cost factor that makes repricing quick. If the supplier’s price changes, multiply the factor by the new price and the card is updated without redoing the test.

Keeping the card honest

Small items

Spices, oil in the pan and a pinch of salt are the usual argument. The Penn State chapter does not offer a special rule for them. It simply lists them as lines, paprika and sherry among them in the Newburg. That is a defensible habit: put them on the card at their real cost per unit and let them be small numbers. What matters is that the same method is used on every card, so the cards can be compared with each other.

Recosting

Prices move. The Penn State chapter says standard portion costs should be recalculated regularly, especially in a period of high inflation, while a stable market may need updates only every few months. A card with a date on it tells the reader how much to trust it. If your costs are in a spreadsheet, one price cell can feed every card that uses the ingredient. The chapter notes that cards can be kept in a point-of-sale database or a spreadsheet linked to inventory so the costs update on their own.

The order guide is where the new prices arrive. I covered how to keep one in Writing a Weekly Order Guide for a Restaurant. When a number on that sheet jumps, the cards that use that item are the ones to rerun first.

Date the card and name the version

Put the date of the prices on the card, and the date of the last yield test beside any trimmed item. Two cards for the same dish with different dates are not a contradiction; they are a history. The old one shows what the dish cost when the menu price was set, and the new one shows what it costs now. The gap between them is the argument for or against a price change, and it is a better argument than a feeling.

Who writes it

The person who knows how the dish is actually built, standing at the station with a scale, writes the card. Someone in an office with a recipe from a book writes a fiction. The recipe on paper and the recipe on the line differ in small ways, a heavier hand with the cheese, a larger scoop, and the card has to describe the line. Weigh what the cook actually uses for a few portions and use the average.

Using the numbers

What to do with a high cost percentage

A dish with a high food cost can be fixed three ways: change the recipe, change the portion or change the price. All three have costs the card cannot show. A smaller portion may sell fewer. A higher price may sell fewer. A cheaper ingredient may change the plate in a way that regulars notice on the first day. The card shows the arithmetic and leaves the decision where it was, with whoever runs the place.

There is also a reasonable case for leaving a dish alone. Some items are on the menu because people come in for them, and they bring in the other orders with them. The Penn State chapter uses the card to get from ingredient prices to a food cost percentage, and it does that job well, but the people reading the percentage should remember what it leaves out.

Where this goes next

Once the cards exist, they feed everything else: menu pricing, specials, the question of which ingredient to buy in bulk. A set of cards in a binder is also a record. If the cook who knows the recipe leaves, the card keeps the quantities.
