Cooking with olive oil
Consuming Extra Virgin Olive Oil Without Turning It Into a Ritual
Most people buy a bottle and then use it twice. Here is where extra virgin olive oil actually fits across an ordinary Malaysian week, measured per dish rather than per person.

The short answer
Extra virgin olive oil goes into a week most easily as a finishing oil rather than a cooking one: a spoonful over hot rice, on roti, into a sambal after the heat is off, over grilled fish, or in a dressing. Measure it per dish, never per person, and keep the bottle shut.
A bottle arrives, gets used in one salad, and then sits at the back of the cupboard until the flavour has gone quiet. That is the usual story, and it is a storage problem dressed up as a habit problem.
This is about where the oil actually goes across an ordinary week, in food terms and in dish-sized quantities.
Raw or heated, what changes?
Raw, you get everything the oil has: the grassy or fruity smell, the bitterness, the peppery catch at the back of the throat. Heated, the aroma goes first and the finish softens, and the higher the pan the less of it reaches the plate. Nothing becomes unsafe, it simply becomes quieter.
So the easiest way to get value from a bottle is to add it after the heat rather than before it. The oil then behaves like a seasoning, which is roughly how it is used around the Mediterranean.

Where does it fit in a Malaysian week?
In more places than people expect, and mostly in slots a household already has. Anywhere a dish currently gets a spoon of something rich at the end, olive oil can take that job without changing the recipe underneath it. The point is the finish, not a substitution.
| Meal | How it goes in | How much per dish |
|---|---|---|
| Hot white rice | Stirred through just before serving | About a teaspoon per bowl |
| Roti or toast | Poured into a shallow saucer for dipping | A tablespoon for the table |
| Sambal or a stir-fry | Stirred in after the heat is off | A teaspoon, off the flame |
| Grilled fish or chicken | Drizzled over the plated dish | A teaspoon per portion |
| Salad or cold vegetables | Whisked with acid into a dressing | Two tablespoons for four |

Why measure per dish, not per person?
Because a dish has a right amount and a person does not. A saucer for dipping serves whoever is at the table. A dressing is sized to the bowl of leaves. Thinking in daily allowances turns a cooking ingredient into a regimen, which is not what this oil is, and not something a food article can prescribe.
If the underlying question is really about diet, that is one for a doctor or a registered dietitian. The careful version of what is and is not known is in the health benefits article.

How long should a bottle last?
Used raw in teaspoons and tablespoons, far longer than most people assume, which is why bottle size is really a freshness question. An unopened bottle keeps up to around eighteen months. Once opened, the flavour holds for roughly two months, and after that it flattens whether or not the bottle is full.
So the size to buy is whichever you will finish inside that window. A larger bottle is cheaper per litre and worse value if the last third has already gone quiet. What size to buy works through it.

What is the one habit that ruins it?
Leaving the bottle open beside the stove. Between the warm air, the light and the open neck, an oil kept there loses more in a fortnight than any single pan takes from it. It is the most common way a household wastes the difference it paid for.
- Cap it after every pour, not at the end of cooking
- Keep it in a cupboard away from the hob, not on the counter beside it
- Judge it by smell rather than by a date on the label
- The refrigerator is unnecessary, though not harmful, and cold oil clouds until it warms

The honest version
Treat it as a finishing seasoning rather than a cooking oil and it will get used, taste of something, and be finished before it flattens. Pick two slots from the table above, keep the bottle shut and away from the stove, and the rest looks after itself.
