Questions & Answers about kono korokke ni wa soosu o sukoshi kakeru dake de juubun oishii.

Why is には used after このコロッケ?

には is に + は.

Here, に marks the target/surface that the sauce is put on: this croquette.
Then は adds a topic or contrast nuance.

So このコロッケには feels like:

• as for this croquette
• on this croquette
• when it comes to this croquette

It can also imply contrast, like: This croquette, at least, only needs a little sauce.

Without は, このコロッケに would sound more neutral and purely grammatical. With には, the speaker is highlighting this croquette in particular.

Why is it ソースを少しかける and not ソースが少しかける?

Because ソース is the thing being applied, so it is the direct object of かける.

• ソースをかける = to pour/apply sauce
• を marks what is being put on something

So:

• このコロッケにソースをかける = put sauce on this croquette

Using が here would not fit normal grammar for this verb in this sentence.
