A mi prima no le gusta la coliflor, pero la come si la ponemos con salsa de queso.

Because Spanish often uses an indirect object phrase to show who is affected, especially with verbs like gustar.

In A mi prima no le gusta la coliflor:

• A mi prima = to my cousin
• le = to her

So A mi prima repeats and clarifies who le refers to. This is very common in Spanish.

You could say just No le gusta la coliflor if it is already clear who le means, but A mi prima makes it explicit and can also add emphasis.

Gustar does not work like English to like.

English says:

• My cousin doesn’t like cauliflower

Spanish structures it more like:

• Cauliflower is not pleasing to my cousin

So in A mi prima no le gusta la coliflor:

• la coliflor is the grammatical subject
• le means to her
• gusta means is pleasing

That is why Spanish learners often feel that the sentence is “backwards” compared with English.

Because la coliflor is singular.

With gustar, the verb agrees with the thing that is liked or disliked:

• Me gusta la coliflor = I like cauliflower
• Me gustan las verduras = I like vegetables

Here the subject is la coliflor, one singular thing, so the verb is gusta.

Spanish often uses the definite article with foods, school subjects, languages, and other nouns when speaking generally.

So:

• Me gusta el café
• No come la carne
• A mi prima no le gusta la coliflor

In English, we often drop the article in general statements, but Spanish usually keeps it.

Here la coliflor means cauliflower in general, not necessarily one specific cauliflower sitting on the table.

Because the two verbs take different kinds of objects.

In le gusta:

• le is an indirect object pronoun
• it refers to mi prima
• literally: it is pleasing to her

In la come:

• la is a direct object pronoun
• it refers to la coliflor
• literally: she eats it

So:

• le = to her
• la = it, referring to the cauliflower

This difference is very important in Spanish.

Because Spanish often leaves subject pronouns out when the verb ending already shows the person.

Here:

• come = she eats / he eats / you eat depending on context
• ponemos = we put / we serve

The context tells us:

• come refers to mi prima
• ponemos means we

Spanish only adds subject pronouns like ella or nosotros when needed for emphasis, contrast, or clarity.

So ella la come is possible, but it is less neutral and more emphatic.

Because in Spanish, object pronouns normally go before a conjugated verb.

So:

• la ponemos = we put it / we serve it
• not ponemos la in this structure

The la replaces la coliflor.

You could also use the full noun instead of the pronoun:

• si ponemos la coliflor con salsa de queso

But once la coliflor has already been mentioned, Spanish often uses the pronoun la to avoid repetition.

Because after si meaning if, Spanish normally uses the indicative for real or possible conditions.

Here the idea is a normal, realistic condition:

• ...pero la come si la ponemos con salsa de queso
• ...but she eats it if we serve it with cheese sauce

That is why ponemos is correct.

Compare:

• si la ponemos... = if we put/serve it...
• si la pusiéramos... = if we were to put/serve it... (more hypothetical, less direct)

So the sentence uses the ordinary present indicative because it is talking about a real situation.

Not completely literally.

Poner often means to put, but in food contexts it can also mean something like:

• to serve
• to put on
• to present
• to prepare in a certain way

So si la ponemos con salsa de queso means something like:

• if we serve it with cheese sauce
• if we put cheese sauce on it

It sounds natural in Spanish even though a word-for-word translation with put may sound a bit odd in English.

Because de is commonly used to show what something is made of or what type of thing it is.

So:

• salsa de queso = cheese sauce
• literally, sauce of cheese

This is the normal expression.

Salsa con queso would sound more like sauce with cheese in it, which is possible in some contexts, but it is not the usual way to name cheese sauce.

Because si without an accent means if.

Spanish distinguishes:

• si = if
• sí = yes

So in this sentence:

• si la ponemos con salsa de queso = if we serve it with cheese sauce

The accent matters, because sí would be a different word.

Yes. Spanish word order is more flexible than English, especially with phrases like A mi prima.

For example, these are also possible:

• La coliflor no le gusta a mi prima, pero la come si la ponemos con salsa de queso.
• A mi prima la coliflor no le gusta, pero la come si la ponemos con salsa de queso.

They all mean basically the same thing, but the emphasis changes slightly.

The original version is very natural and straightforward.
