Char Siu: The Restaurant Price Versus the Kitchen Price
A batch cooked once and divided across four portions
The delivery order replaced by a wok and a pot of stock
A wet market at seven, and a plastic bag of bones for stock.
Char siu is priced by the ingredient, the batch and the hour, and the batch is what makes it cheap.
Prices for char siu arrive in ranges rather than headlines, and the ranges are what a household can plan with.
A restaurant charges for the table and the washing-up, and neither is in the ingredients for char siu.
What does char siu cost?
What char siu costs is a set of 5 lines rather than a headline price, and the basis column is the part to read.
The key ingredient sets the floor of the price, and the rest of the dish is cheap by comparison.
A restaurant charges for the rent, the labour and the washing-up, and none of them are in the ingredients for char siu.
A household should check the current price before it pays, and the table is a way to know which line to check first.
The price of the dish splits into ingredients and labour, and a household supplies the second one.
A dish cooked in a batch is cheap for two days and tiring by the third.
| Line | Typical range | Basis |
|---|---|---|
| Wok or steamer | $25–80 | one purchase |
| Takeout version | $12–30 | typical |
| Restaurant plate | $10–25 | typical |
| Key ingredient | $3–8 | per pack |
| Ingredients, per serving | $2–5 | market prices |
The smallest honest budget
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 total moves with the city and the season, and the two lines that move most are the two in the sum.
Two lines are enough to see the shape, and the shape is what decides whether the purchase happens.
The ingredient is the line that moves in the dish, and the restaurant's rent is the line that does not.
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
Every price for the dish has an alternative next to it, and the alternative is what the household is really choosing between.
The table lists the substitutes, and the cheapest substitute is usually the one that costs an hour rather than a fee.
A household that can name the substitute can usually name the saving, and the saving is the gap between the two lines.
The ingredients for the dish are cheaper at a market than at a convenience store, and the shop is the price.
| Alternative | Typical range |
|---|---|
| A delivery order | $12–30 |
| A frozen version | $5–12 |
| A restaurant dinner | $25–60 |
Six moves that change the number
The order matters less than the first move, which is to know which line is fixed and which is optional.
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.
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.
Cook the rice before the wok. The cooker works while the pan is busy, and the meal lands together.
Buy the vegetables twice a week. A wet market is a short walk, and fresh is a frequency rather than a store.
A household that writes the range down before it shops is already ahead of the one that guesses.
When it is not worth it
A fair account of the dish has to include the parts that do not work.
A wok burner runs hot, and a kitchen with one window holds the smoke, and the smoke is the cost of the dish.
A dish that needs a wok needs a burner that reaches wok heat, and an induction hob does not.
A household of one cooks a batch and eats it three times, and the third time is the limit.
The ingredients for the dish are cheap at a market and expensive at a convenience store, and the shop is the price.
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 cheap cut of meat for the dish costs more time, and the time is the line a recipe leaves out.
The wok for the dish needs a burner that reaches wok heat, and an induction hob does not.
The timing question
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.
A household that plans by the season pays the ordinary price, and the ordinary price is the one the table describes.
Five checks before the payment
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.
Keep the receipt for the big shop. A receipt for the the dish shopping shows which line moved and by how much.
Price the batch, not the plate. One shopping trip for the dish divides across four portions, and the portion is the real cost.
Taste before the salt. The sauce for the dish reduces, and the salt added early reduces with it.
Use the whole vegetable. Stems and peel for the dish go into the pot, and the bin stays empty.
Check the equipment you own. A wok and a steamer cover most of the dish, and the rest is a gadget for one job.
The five checks cost nothing, and together they are worth more than any discount a household negotiates.
Who pays?
The cost falls on the person who books it, and the benefit falls on everyone at the table.
The household that splits the cost also splits the decision, and the split is the argument.
The household matters less than the number of people it brings to the table.
The person who cooks the dish is often not the person who shops for it.
What's worth taking?
The gap between a restaurant plate of the dish and the homemade version is the rent, and the rent is not food.

The search for the dish ends with a number, and the number is easier to check than to argue about.
What the dish saves is the labour charge, and the labour is the hour at the board.
A restaurant version of the dish uses more oil and salt, and the homemade version is cheaper partly because it uses less.
The household that cooks the dish in a batch pays the ingredient price and not the restaurant one.
The cheap version of the dish costs less per plate and more per hour, and the hour is the trade.
A batch of the dish divides the shopping across four portions, and the division is the saving.
