Saya gaul tomato dan kubis pada waktu pagi, lalu saya simpan dalam peti sejuk sampai malam.

Here, gaul means to mix, toss, or combine by stirring/turning things together.

With food, gaul often suggests physically mixing ingredients so they are evenly combined, which is why it works well for something like tomato dan kubis.

It is similar to campur, but not always identical:

• campur = a general mix / combine
• gaul = often mix/toss thoroughly, especially with food

Also, gaul can mean to socialize / hang out in other contexts, so the surrounding words are important.

Malay usually does not mark plural the way English does.

So:

• tomato can mean tomato or tomatoes
• kubis can mean cabbage or cabbages, depending on context

Malay often leaves number to context. If the meaning is already clear, no extra plural marking is needed.

If a speaker really wants to emphasize plurality, Malay can use:

• tomato-tomato
• beberapa biji tomato
• banyak tomato

But in normal sentences, plain nouns are very common.

Yes, it could just say pagi.

• pada waktu pagi = in the morning
• pagi = morning / this morning, depending on context

The longer version sounds a bit more explicit and slightly more formal or careful. In everyday speech, many speakers would simply say:

• Saya gaul tomato dan kubis pagi tadi...
• Saya gaul tomato dan kubis pada pagi hari...
• Saya gaul tomato dan kubis pagi...

So pada waktu pagi is correct, but a little more formal than necessary in casual conversation.

In this sentence, lalu means then, and then, or after that.

It links two actions in sequence:

1. Saya gaul tomato dan kubis pada waktu pagi
2. lalu saya simpan dalam peti sejuk sampai malam

So the sense is: I mixed the tomato and cabbage in the morning, then I stored it/them in the fridge until night.

A useful warning: lalu can also have other meanings in other contexts, such as to pass by. But here it is clearly a connector meaning then/after that.

Because Malay often repeats the subject in a new clause, especially in clear, careful writing.

So:

• ..., lalu saya simpan ...

is completely normal.

Malay can sometimes omit repeated subjects if the meaning is obvious, but repeating saya helps make the sentence structure clear. It is especially common when two clauses are joined by words like lalu, kemudian, or dan kemudian.

So the repeated saya is not strange or redundant; it is natural Malay.

Good question. Malay often leaves out an object if it is already obvious from context.

Here, after:

• Saya gaul tomato dan kubis ...

the listener already knows what is being talked about. So:

• lalu saya simpan dalam peti sejuk

naturally means:

• then I stored it/them in the fridge

The omitted object is understood as the tomato and cabbage or the mixture.

If you wanted to say it fully, you could say:

• lalu saya simpan tomato dan kubis itu dalam peti sejuk
• lalu saya simpan campuran itu dalam peti sejuk

But leaving it out is very normal.

Yes. Both are possible, but they feel slightly different.

• dalam peti sejuk = in the fridge
• di dalam peti sejuk = also in the fridge, but a bit more explicit about location

After a verb like simpan (store/keep), Malay often uses just dalam very naturally:

• simpan dalam peti sejuk
• letak dalam beg
• masukkan dalam kotak

So simpan dalam peti sejuk is perfectly idiomatic.

If you say di dalam peti sejuk, it is still correct, just a little fuller.

Sampai malam means until evening/night.

The word malam covers the part of the day after sunset and into the night, so English translation depends on context. Sometimes evening fits better; sometimes night does.

So this phrase means the food stayed in the fridge until that later time in the day.

Also:

• sampai = until / up to / as far as
• A more formal alternative is hingga malam

Malay verbs usually do not change form for tense the way English verbs do.

So:

• gaul
• simpan

stay the same whether the action is past, present, or future. Time is usually understood from context or from time expressions such as:

• pada waktu pagi
• sampai malam

Because of those phrases, the listener understands the sequence of events without needing special past-tense verb forms.

This is very typical of Malay:

• time words do a lot of the work
• verb forms stay simple

The sentence is understandable and grammatically fine. But in everyday speech, some speakers might choose slightly more casual wording.

For example:

• Saya gaul tomato dan kubis pada waktu pagi, kemudian saya simpan dalam peti sejuk sampai malam.
• Saya gaul tomato dan kubis pagi tadi, lepas tu saya simpan dalam peti sejuk sampai malam.

Some small notes:

• lalu can sound a bit more written or narrative than kemudian or lepas tu
• pada waktu pagi is correct, but a little formal
• sampai malam is natural and common

So the original sentence is good, but it leans slightly toward careful, standard wording rather than very casual conversation.

Yes, it can.

Because gaul often suggests mixing ingredients together, many learners will naturally read this as something like:

• mixing tomato and cabbage together
• tossing them together
• preparing a simple salad-like mixture

However, the sentence itself does not force only one interpretation. It simply says the speaker mixed those ingredients and later stored them in the fridge. The exact dish depends on the wider context.
