Siu Mai: What a Weekend Batch Saves
A batch cooked once and divided across four portions
The delivery order replaced by a wok and a pot of stock
A wok on a burner, a board of chopped scallion and a rice cooker on warm.
The cost of siu mai is the shopping plus the cooking, and the cooking is the part a restaurant charges for.
Prices for siu mai arrive in ranges rather than headlines, and the ranges are what a household can plan with.
The ingredient is the line that moves in siu mai, and the restaurant's rent is the line that does not.
Where the money goes
For siu mai, the cost splits into 5 lines, and the table is the only honest way to show them.
A batch of siu mai divides the shopping across four portions, and the division is the saving.
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.
A restaurant charges for the table and the washing-up, and neither is in the ingredients for the dish.
The ingredients for the dish are cheaper at a market than at a convenience store, and the shop is the price.
| Line | Typical range | Basis |
|---|---|---|
| Ingredients, per serving | $2–5 | market prices |
| Restaurant plate | $10–25 | typical |
| Takeout version | $12–30 | typical |
| Key ingredient | $3–8 | per pack |
| Wok or steamer | $25–80 | one purchase |
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 total moves with the city and the season, and the two lines that move most are the two in the sum.
The sum is the minimum a household should expect, and the minimum is the number that survives a bad month.
The cheap version of the dish costs less per plate and more per hour, and the hour is the trade.
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 does it replace?
Every price for the dish has an alternative next to it, and the alternative is what the household is really choosing between.
The substitute is not identical: it trades one kind of cost for another, and the trade is the point.
The substitute is rarely identical, and the difference is usually the hour rather than the money.
The wok for the dish needs a burner that reaches wok heat, and an induction hob does not.
| Alternative | Typical range |
|---|---|
| A restaurant dinner | $25–60 |
| A delivery order | $12–30 |
| A frozen version | $5–12 |
The practical version
Every step here is a decision rather than a purchase, and the first one is to price the line before paying it.
Cut everything before the pan is hot. The dish cooks in minutes, and there is no time to chop once it starts.
Make stock from the bones. Bones, ginger and water, boiled down and frozen in cups.
Salt at the end. The sauce reduces, and the salt added early reduces with it.
Cook the rice before the wok. The cooker works while the pan is busy, and the meal lands together.
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.
What the dish saves is the labour charge, and the labour is the hour at the board.
What the price does not include
A fair account of the dish has to include the parts that do not work.
A household of one cooks a batch and eats it three times, and the third time is the limit.
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.
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.
The ingredients for the dish are cheap at a market and expensive at a convenience store, and the shop is the price.
A dish cooked in a batch is cheap for two days and tiring by the third.
A restaurant version of the dish uses more oil and salt, and the homemade version is cheaper partly because it uses less.
The timing question
The calendar is the cheapest lever in the dish, and it is the one a household can pull without spending anything.
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.
The ingredients for the dish are cheapest in the season they are grown.
The date is the only line in the table that can be moved without buying anything different.
What the quote leaves out
Before paying for the dish, five checks change the total more than any discount.
Buy bones for stock. A bag of bones costs less than a carton of stock and makes more of it.
Cool the rice quickly. Rice for the dish left warm is a food-safety risk rather than a shortcut.
Cook one extra portion. The second portion of the dish is tomorrow's lunch at the same cost.
Freeze in portions. A batch of the dish frozen in cups is a week of weeknights, and the freezer is the pantry.
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.
A household that runs the five checks once runs them on the next purchase without thinking.
The household behind the bill
The person who pays for the dish is not always the person who chooses it, and the gap is where budgets slip.
A household with an older parent carries a different version of the bill, and a household with a child carries another.
A household with more people uses more of the lines and none of the fixed ones, and that is the whole difference.
A household of one cooks the dish twice and eats it three times, and the third time is the limit.
The one line to keep
The household that cooks the dish in batches pays the ingredient price and not the restaurant one.

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.
The price of the dish splits into ingredients and labour, and a household supplies the second one.
The household that cooks the dish in a batch pays the ingredient price and not the restaurant one.
A cheap cut of meat for the dish costs more time, and the time is the line a recipe leaves out.
