Yu Xiang Eggplant: 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 steamer basket over a pot, and a table set with four dishes and a soup.
The cost of yu xiang eggplant is the shopping plus the cooking, and the cooking is the part a restaurant charges for.
Prices for yu xiang eggplant arrive in ranges rather than headlines, and the ranges are what a household can plan with.
The price of yu xiang eggplant splits into ingredients and labour, and a household supplies the second one.
What does yu xiang eggplant cost?
For the dish, the cost splits into 5 lines, and the table is the only honest way to show them.
A restaurant charges for the rent, the labour and the washing-up, and none of them are in the ingredients for the dish.
A batch of the dish divides the shopping across four portions, and the division is the saving.
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.
A dish cooked in a batch is cheap for two days and tiring by the third.
| Line | Typical range | Basis |
|---|---|---|
| Key ingredient | $3–8 | per pack |
| Ingredients, per serving | $2–5 | market prices |
| Wok or steamer | $25–80 | one purchase |
| Takeout version | $12–30 | typical |
| Restaurant plate | $10–25 | typical |
The smallest honest budget
The arithmetic is easier with two lines than with five: ingredients, per serving ($2–5) plus key ingredient ($3–8) is $5–13, and the rest is discretionary.
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 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 |
Cheap against convenient
The comparison that matters is not cheap against expensive, it is this route against that one.
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 cheap cut of meat for the dish costs more time, and the time is the line a recipe leaves out.
| Alternative | Typical range |
|---|---|
| A restaurant dinner | $25–60 |
| A frozen version | $5–12 |
| A delivery order | $12–30 |
What to do, in order
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.
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.
Cut everything before the pan is hot. The dish cooks in minutes, and there is no time to chop once it starts.
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.
The household that cooks the dish in a batch pays the ingredient price and not the restaurant one.
Where does it go wrong?
A fair account of the dish has to include the parts that do not work.
Rice left warm is a food-safety risk, and a household should cool it quickly and refrigerate it.
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.
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.
The wok for the dish needs a burner that reaches wok heat, and an induction hob does not.
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.
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.
Price the batch, not the plate. One shopping trip for the dish divides across four portions, and the portion is the real cost.
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.
Check the per-portion cost. A restaurant plate of the dish costs several times the ingredients, and the gap is the rent.
Freeze in portions. A batch of the dish frozen in cups is a week of weeknights, and the freezer is the pantry.
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?
The person who pays for the dish is not always the person who chooses it, and the gap is where budgets slip.
The household that splits the cost also splits the decision, and the split is the argument.
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 to do next
A household that freezes half the batch of the dish buys a weeknight for the price of a container.

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 household that writes the range down before it shops is already ahead of the one that guesses.
The ingredients for the dish are cheaper at a market than at a convenience store, and the shop is the price.
A restaurant charges for the table and the washing-up, and neither is in the ingredients for the dish.
The price of the dish splits into ingredients and labour, and a household supplies the second one.
