Peking Duck: Cooking It Well on a Small Budget
A batch cooked once and divided across four portions
The delivery order replaced by a wok and a pot of stock
A steamer basket over a pot, and a table set with four dishes and a soup.
Peking duck is priced by the ingredient, the batch and the hour, and the batch is what makes it cheap.
Prices for peking duck arrive in ranges rather than headlines, and the ranges are what a household can plan with.
The ingredient is the line that moves in peking duck, and the restaurant's rent is the line that does not.
Where the money goes
What peking duck costs is a set of 5 lines rather than a headline price, and the basis column is the part to read.
A restaurant charges for the rent, the labour and the washing-up, and none of them are in the ingredients for peking duck.
The key ingredient sets the floor of the price, and the rest of the dish is cheap by comparison.
Treat every figure as a typical range, because the same line is a different number in the next city and the next season.
The cheap version of the dish costs less per plate and more per hour, and the hour is the trade.
The wok for the dish needs a burner that reaches wok heat, and an induction hob does not.
| Line | Typical range | Basis |
|---|---|---|
| Restaurant plate | $10–25 | typical |
| Takeout version | $12–30 | typical |
| Wok or steamer | $25–80 | one purchase |
| Ingredients, per serving | $2–5 | market prices |
| Key ingredient | $3–8 | per pack |
A worked example
Take two lines of the dish: ingredients, per serving at $2–5 and key ingredient at $3–8. Together they run $5–13 before anything optional.
The pair is the minimum a household should expect to spend on the dish, and the optional lines are where the budget flexes.
A budget built on two lines is more honest than one built on a headline, and easier to check.
A restaurant charges for the table and the washing-up, and neither is in the ingredients for the dish.
Add the third line, takeout version at $12–30, and the minimum rises to $17–43 before anything optional.
| Line | Typical range |
|---|---|
| Ingredients, per serving | $2–5 |
| Key ingredient | $3–8 |
| Minimum total | $5–13 |
What a household gives up instead
A household does not buy the dish in isolation, it buys it instead of something else.
Some of these alternatives save money and cost time, and the exchange rate between the two is the decision.
A household that can name the substitute can usually name the saving, and the saving is the gap between the two lines.
A restaurant version of the dish uses more oil and salt, and the homemade version is cheaper partly because it uses less.
| Alternative | Typical range |
|---|---|
| A frozen version | $5–12 |
| A restaurant dinner | $25–60 |
| A delivery order | $12–30 |
Six moves that change the number
The moves below are the ones that change the number, in the order a household makes them.
Make stock from the bones. Bones, ginger and water, boiled down and frozen in cups.
Cook one extra portion. The second portion is tomorrow's lunch at the same cost.
Buy the vegetables twice a week. A wet market is a short walk, and fresh is a frequency rather than a store.
Cook the rice before the wok. The cooker works while the pan is busy, and the meal lands together.
Salt at the end. The sauce reduces, and the salt added early reduces with it.
Cut everything before the pan is hot. The dish cooks in minutes, and there is no time to chop once it starts.
The household that cooks the dish in a batch pays the ingredient price and not the restaurant one.
When it is not worth it
The ways the dish goes wrong are ordinary, and most of them are visible before the money is spent.
Rice left warm is a food-safety risk, and a household should cool it quickly and refrigerate it.
A restaurant version uses more oil and more salt, and the homemade version is cheaper partly because it uses less.
A wok burner runs hot, and a kitchen with one window holds the smoke, and the smoke is the cost of the dish.
A household of one cooks a batch and eats it three times, and the third time is the limit.
A dish that needs a wok needs a burner that reaches wok heat, and an induction hob does not.
The ingredients for the dish are cheap at a market and expensive at a convenience store, and the shop is the price.
A cheap cut of meat for the dish costs more time, and the time is the line a recipe leaves out.
The ingredients for the dish are cheaper at a market than at a convenience store, and the shop is the price.
When to buy
Timing changes the number more than bargaining does.
The ingredients for the dish are cheapest in the season they are grown, and the frozen version is the off-season answer.
A batch cooked on Sunday covers two weekdays, and the weekdays are where the takeaway budget goes.
A batch of the dish cooked on Sunday covers two weekdays, and the weekdays are where the takeaway budget goes.
Booking inside the quiet window is the whole saving, and the quiet window is published in advance.
What should you check before paying?
Before paying for the dish, five checks change the total more than any discount.
Cook one extra portion. The second portion of the dish is tomorrow's lunch at the same cost.
Check the equipment you own. A wok and a steamer cover most of the dish, and the rest is a gadget for one job.
Cool the rice quickly. Rice for the dish left warm is a food-safety risk rather than a shortcut.
Taste before the salt. The sauce for the dish reduces, and the salt added early reduces with it.
Keep the receipt for the big shop. A receipt for the the dish shopping shows which line moved and by how much.
Compare the takeaway price. A delivery order for the dish carries a fee, a mark-up and a wait, and the wait is not refunded.
A household that runs the five checks once runs them on the next purchase without thinking.
Who pays?
A household of one buys the dish differently from a household of five, and the difference is in the optional lines.
A single person can absorb a bad buy, and a family cannot, which is why the family reads the table first.
The table does not change with the household, but the number of lines a household uses does.
The person who cooks the dish is often not the person who shops for it.
What's worth taking?
What the dish saves is the labour charge, and the labour is the hour at the board.

The search for the dish ends with a number, and the number is easier to check than to argue about.
A household that writes the range down before it shops is already ahead of the one that guesses.
A dish cooked in a batch is cheap for two days and tiring by the third.
A batch of the dish divides the shopping across four portions, and the division is the saving.
The price of the dish splits into ingredients and labour, and a household supplies the second one.
The ingredient is the line that moves in the dish, and the restaurant's rent is the line that does not.
