oirang tomato-e sogeumeul jogeum neohgo jal seokkeoyo.

-랑 means and in a casual, spoken style.

So:

• 오이랑 토마토 = cucumbers and tomatoes

A few similar ways to say and are:

• 오이와 토마토 / 오이과 토마토 → more formal/written
• 오이하고 토마토 → common in speech
• 오이랑 토마토 → very natural in everyday speech

Also note that -랑 attaches directly to a noun:

• 오이 + 랑 → 오이랑

Here, 에 marks the place or target that something is added to.

• 오이랑 토마토에 소금을 넣어요 = put salt on / into the cucumbers and tomatoes

So:

• 소금 is the thing being added
• 오이랑 토마토에 is where it is being added

That is why 소금 gets the object marker -을:

• 소금을

If you said 오이랑 토마토를, that would make cucumbers and tomatoes the direct object instead.

In the second part, 잘 섞어요, the object is omitted because it is already understood: you are mixing the cucumbers and tomatoes with the salt.

In this sentence, 에 shows the destination or target of the action 넣다 (to put in / add).

So:

• 오이랑 토마토에 소금을 넣고 = add salt to the cucumbers and tomatoes

With 넣다, Korean often uses:

• A에 B를 넣다 = put/add B into/to A

Examples:

• 물에 설탕을 넣어요. = Add sugar to the water.
• 국에 소금을 넣어요. = Add salt to the soup.

So this sentence follows the same pattern.

Because 소금 is the direct object of 넣다.

The pattern is:

• A에 B를 넣다
• add B to A

In this sentence:

• A = 오이랑 토마토에
• B = 소금을

So literally, the structure is:

• to the cucumbers and tomatoes, add salt

That is why 소금 takes -을.

조금 means a little or a bit.

Here it modifies how much salt is added:

• 소금을 조금 넣고 = add a little salt and...

Its position is very natural in Korean. It comes before the verb it relates to:

• 소금을 조금 넣고
• literally: salt a little add-and

You could think of it as an adverb-like word describing the amount of the action.

넣고 is the verb 넣다 (to put in, add) plus -고.

• 넣다 = to add / put in
• 넣고 = add and...

The -고 ending links one action to the next:

• 소금을 조금 넣고 잘 섞어요
• add a little salt and mix well

It is a very common way to connect actions in sequence.

Examples:

• 문을 열고 들어가요. = Open the door and go in.
• 물을 끓이고 면을 넣어요. = Boil the water and add the noodles.

Here, -고 connects two actions in order:

1. add a little salt
2. mix well

So in this sentence, it works like and then.

However, -고 does not always mean a simple English and in every situation. Its main job is just to link clauses. Depending on context, it can feel like:

• and
• and then
• sometimes just a neutral connection between two actions

In recipe instructions like this, it usually suggests sequence.

잘 usually means well.

So:

• 잘 섞어요 = mix well

It is an adverb modifying the verb 섞어요.

Very common uses of 잘:

• 잘 먹어요 = eat well
• 잘해요 = do well
• 잘 자요 = sleep well
• 잘 섞어요 = mix well

In cooking instructions, 잘 often means thoroughly or evenly.

The dictionary form is 섞다, which means to mix.

Conjugation:

• 섞다 → stem 섞-
• add -어요
• 섞어요

So 섞어요 is the polite present-style form.

Because Korean recipes and instructions often use this polite style, 섞어요 can sound like:

• mix
• mix well
• please mix well

depending on context.

This is a very common thing in Korean.

In recipes, demonstrations, and instructional writing, Korean often uses the polite -아요/어요 form instead of a stronger command form. So even though 섞어요 is grammatically a polite present form, in context it functions like an instruction:

• mix well

This style sounds natural and friendly in recipe directions.

Compare:

• 섞어요 → polite instructional style, common in recipes
• 섞으세요 → more direct polite command: please mix
• 섞어라 / 섞어 → much more direct, not typical for recipe writing

The subject is omitted, which is very normal in Korean.

In English, you might expect:

• You add a little salt and mix well.

But in Korean, if the subject is obvious from context, it is usually left out. In a recipe or instruction, the implied subject is often:

• you
• or more loosely, the cook / the person following the steps

So the sentence does not need an explicit subject.

Because it is understood from context.

After hearing:

• 오이랑 토마토에 소금을 조금 넣고...

the listener already knows what is being mixed: the cucumbers, tomatoes, and salt together.

So Korean naturally omits the object in the second verb:

• 잘 섞어요 = mix well

If you wanted to say it more explicitly, you could include the object, but it is often unnecessary.

This kind of omission is extremely common in Korean when the meaning is clear.

Korean nouns often do not need explicit plural marking when the meaning is clear.

So:

• 오이 can mean cucumber or cucumbers
• 토마토 can mean tomato or tomatoes

In a cooking sentence like this, the context tells you that ingredients are being referred to, so English may translate them as plurals.

Korean does have a plural marker -들, but it is not usually needed here.

Yes. Common replacements are:

• 오이하고 토마토에 소금을 조금 넣고 잘 섞어요.
• 오이와 토마토에 소금을 조금 넣고 잘 섞어요.

They all mean basically the same thing, but the tone changes a little:

• -랑 → casual, natural spoken Korean
• -하고 → also common and conversational
• 와/과 → more formal or written

In everyday speech, -랑 and -하고 are especially common.

Yes, it is natural and easy to understand.

It has several features that are typical of recipe/instruction Korean:

• ingredients named first
• 넣고 to link steps
• 잘 for well/thoroughly
• polite -어요 style for instructions
• omitted subject and omitted repeated object

So it sounds like a normal recipe step:

• add a little salt to the cucumbers and tomatoes, and mix well
