Monosodium Glutamate: The Ingredient Worth Paying For
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 monosodium glutamate is the shopping plus the cooking, and the cooking is the part a restaurant charges for.
Prices for monosodium glutamate arrive in ranges rather than headlines, and the ranges are what a household can plan with.
The ingredient is the line that moves in monosodium glutamate, and the restaurant's rent is the line that does not.
What a household actually pays
The bill for monosodium glutamate is a table rather than a number: 5 lines, and only one of them is quoted on a website.
A batch of monosodium glutamate divides the shopping across four portions, and the division is the saving.
A restaurant charges for the rent, the labour and the washing-up, and none of them are in the ingredients for the dish.
A household should check the current price before it pays, and the table is a way to know which line to check first.
The cheap version of the dish costs less per plate and more per hour, and the hour is the trade.
A restaurant version of the dish uses more oil and salt, and the homemade version is cheaper partly because it uses less.
| Line | Typical range | Basis |
|---|---|---|
| Ingredients, per serving | $2–5 | market prices |
| Wok or steamer | $25–80 | one purchase |
| Key ingredient | $3–8 | per pack |
| Restaurant plate | $10–25 | typical |
| Takeout version | $12–30 | typical |
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 pair is the minimum a household should expect to spend on the dish, and the optional lines are where the budget flexes.
The sum is the minimum a household should expect, and the minimum is the number that survives a bad month.
The price of the dish splits into ingredients and labour, and a household supplies the second one.
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 prices the substitute before the purchase usually finds that the expensive version was buying convenience, not quality.
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 delivery order | $12–30 |
| A frozen version | $5–12 |
What to do, in order
Every step here is a decision rather than a purchase, and the first one is to price the line before paying it.
Salt at the end. The sauce reduces, and the salt added early reduces with it.
Cook one extra portion. The second portion is tomorrow's lunch at the same cost.
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.
Make stock from the bones. Bones, ginger and water, boiled down and frozen in cups.
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.
Where does it go wrong?
A fair account of the dish has to include the parts that do not work.
The ingredients for the dish are cheap at a market and expensive at a convenience store, and the shop is the price.
A wok burner runs hot, and a kitchen with one window holds the smoke, and the smoke is the cost of the dish.
Rice left warm is a food-safety risk, and a household should cool it quickly and refrigerate it.
A dish that needs a wok needs a burner that reaches wok heat, and an induction hob does not.
A restaurant version uses more oil and more salt, and the homemade version is cheaper partly because it uses less.
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 cheaper at a market than 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.
What the calendar changes
The calendar is the cheapest lever in the dish, and it is the one a household can pull without spending anything.
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, and the frozen version is the off-season answer.
A batch of the dish cooked on Sunday covers two weekdays, and the weekdays are where the takeaway budget goes.
The date is the only line in the table that can be moved without buying anything different.
Before you pay
Before paying for the dish, five checks change the total more than any discount.
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.
Freeze in portions. A batch of the dish frozen in cups is a week of weeknights, and the freezer is the pantry.
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.
Keep the receipt for the big shop. A receipt for the the dish shopping shows which line moved and by how much.
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.
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 cost of the dish falls on the person at the stove, and the benefit is at the table.
What to do next
A household that prices the dish by the portion rather than the plate keeps the grocery bill flat.

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 dish cooked in a batch is cheap for two days and tiring by the third.
A restaurant charges for the table and the washing-up, and neither is in the ingredients for the dish.
A household that writes the range down before it shops is already ahead of the one that guesses.
