은 is the topic marker. It tells you that 양념 (seasoning/sauce) is the thing the sentence is talking about.

So 이 양념은 means something like:

• As for this seasoning...
• This seasoning...

It does not simply mean subject in the same way English does. It sets the topic and often gives a sense of contrast or focus.

Here, 이 is the subject marker. In this part of the sentence, 고추장 is the thing that goes in / is included.

So the structure is:

• 고추장이 들어가다 = gochujang goes in / is added / is included

A learner might wonder why the sentence has both 은 and 이:

• 양념은 = the overall topic
• 고추장이 = the subject of the smaller clause inside the sentence

This is very common in Korean.

Yes, literally 들어가다 means to go in / enter, but in food-related Korean it very often means:

• to be included
• to go into something as an ingredient

So 고추장이 들어가다 means:

• gochujang is included
• gochujang goes into it
• it contains gochujang

This is a very natural Korean way to talk about ingredients.

Good question. The difference is mainly about point of view.

• 넣다 = to put in something
  
  • focuses on the person doing the action
• 들어가다 = to go in / be included
  
  • focuses on the ingredient becoming part of the dish

So:

• 고추장을 넣어서 = because/after putting in gochujang
• 고추장이 들어가서 = because gochujang is in it / since gochujang is included

In this sentence, 들어가서 sounds natural because the speaker is describing the sauce’s composition, not the cook’s action.

Here -아서 / -어서 connects two parts of the sentence. Very often it means:

• because
• so
• sometimes just and then

In this sentence, it gives a reason:

• 고추장이 들어가서 조금 맵지만 맛있어요
• Because gochujang is included, it’s a little spicy, but it’s tasty

So 들어가서 is not just entered and...; it is functioning as a connector meaning since / because it contains.

Korean often connects clauses directly with verb/adjective endings instead of making two fully separate sentences.

So instead of saying:

• 조금 매워요. 하지만 맛있어요.

Korean can more smoothly say:

• 조금 맵지만 맛있어요.

Here -지만 means but / although and attaches directly to 맵다.

This connected style is very common and usually sounds more natural in written and spoken Korean.

-지만 means but, although, or even though.

It attaches directly to the dictionary form stem:

• 맵다 → 맵지만
• 맛있다 → 맛있지만

So:

• 조금 맵지만 맛있어요 = It’s a little spicy, but it’s tasty

It creates contrast between two ideas:

• spicy
• tasty

In English, but is a separate word. In Korean, it is often attached to the verb or adjective.

Because each part is doing a different job.

• 맵지만: connected clause
  
  • 맵다
    • -지만
  • means it is spicy, but...
• 맛있어요: final polite ending
  
  • 맛있다
    • -어요
  • means it is tasty

Only the final clause needs the final speech-level ending here, because the sentence ends there.

So the pattern is:

• earlier clause: connected form
• final clause: sentence-ending form

That is very typical Korean sentence structure.

조금 literally means a little / a bit.

In this sentence, it modifies 맵다:

• 조금 맵다 = to be a little spicy

It can describe a small degree of something, but it can also soften a statement. So it may sound less strong than simply saying:

• 맵지만 맛있어요 = It’s spicy, but tasty
• 조금 맵지만 맛있어요 = It’s a little spicy, but tasty

So yes, it means a little, but it also helps make the comment sound gentler.

이 is the demonstrative this.

So:

• 이 양념 = this seasoning / this sauce

Korean has a three-way system:

• 이 = this (near the speaker)
• 그 = that (near the listener or already mentioned)
• 저 = that over there (far from both)

So 이 양념은 is simply this seasoning, as for it...

The sentence breaks down like this:

• 이 양념은 = as for this seasoning
• 고추장이 들어가서 = because gochujang is included
• 조금 맵지만 = it is a little spicy, but
• 맛있어요 = it is tasty

So the flow is:

1. introduce the topic
2. give a reason/background
3. add a contrasting point
4. finish with the main statement

This is a very Korean way of building information: background first, main conclusion at the end.

Because Korean often leaves out words that are already understood from context.

Once the sentence establishes the topic as 이 양념은, Korean does not need to keep repeating it. The listener understands that both 맵지만 and 맛있어요 are talking about the same seasoning.

This omission is extremely common in Korean. English usually needs pronouns like it, but Korean often does not.

In careful spelling, it is 맛있어요, but in natural pronunciation it is often heard more like:

• 마시써요

This happens because of Korean sound changes in everyday speech.

So:

• spelling: 맛있어요
• common pronunciation: 마시써요

Learners often get confused because the written form and spoken form are not perfectly identical here. That is normal.
