Пусть брынза и солёная, мне всё равно нравится её вкус.

Here пусть is not a command like Let him go. In this sentence, it works as a concessive particle, meaning something like:

• even though
• granted that
• let it be the case that

So Пусть брынза и солёная... means roughly Even though the cheese is salty... or Granted, the cheese is salty...

This use of пусть is quite common in spoken and written Russian when you admit one fact but then say it does not change your main point.

This is part of a common pattern:

• Пусть X и Y, ...
• Хоть X и Y, ...

It adds a concessive sense: X may be Y, but...

So:

• Пусть брынза и солёная, мне всё равно нравится её вкус.

means something like:

• The brynza may be salty, but I still like its taste.

The и here usually does not mean plain and. It helps form the even though / although structure.

Because it agrees with брынза, which is a feminine singular noun.

So:

• брынза = feminine singular
• солёная = feminine singular form of солёный (salty)

Adjectives in Russian must agree with the noun in:

• gender
• number
• case

Here both are nominative singular feminine.

Брынза is a type of brined white cheese, common in Eastern Europe and the Balkans. In English, there is no perfect one-word equivalent, but it is often compared to feta, though it is not always exactly the same thing.

For grammar purposes, the important thing is:

• брынза is a feminine noun
• it is singular here
• it is the noun that солёная describes

Because нравиться works differently from English to like.

Russian structure is:

• [Something] нравится [to someone]

Literally:

• Its taste is pleasing to me

So:

• мне = to me (dative case)
• нравится = is pleasing
• её вкус = its taste

That is why Russian says:

• Мне нравится её вкус
• literally: Its taste pleases me
• natural English: I like its taste

This is one of the most important patterns for learners to get used to.

Because the grammatical subject is вкус (taste), which is singular.

In Russian, the verb agrees with the thing that is liked, not the person who likes it.

So:

• мне нравится её вкус = I like its taste
  • subject: вкус = singular
  • verb: нравится = singular

Compare:

• Мне нравится сыр. = I like the cheese.
• Мне нравятся сыры. = I like cheeses.

If the thing liked is plural, then you use нравятся.

Here её means its, referring back to брынза.

So:

• её вкус = its taste

Since брынза is grammatically feminine, the possessive pronoun is the same form as her:

• её = her / its

Russian does not have a separate everyday possessive word for its the way English does. Instead, Russian uses the pronoun that matches the noun’s grammatical gender.

Also note that её does not change form here. Russian possessive pronouns его / её / их are indeclinable in this use.

Here всё равно means:

• all the same
• anyway
• still
• nevertheless

So:

• мне всё равно нравится её вкус means
• I still like its taste
• I like its taste anyway

This is a very common expression in Russian.

Be careful: всё равно does not literally mean everything is equal in normal translation, even though that is the literal idea behind it.

Russian word order is more flexible than English word order. This sentence puts the focus naturally on the speaker’s attitude:

• мне всё равно нравится её вкус

That feels like:

• I still like its taste
• with emphasis on still / anyway

You could rearrange it in other ways, for example:

• Её вкус мне всё равно нравится.
• Мне нравится её вкус всё равно. (less natural in many contexts)

The chosen order is very natural because всё равно sits right before нравится, which clearly shows that the liking remains true despite the previous point.

Yes, in many situations you could say:

• Хотя брынза и солёная, мне всё равно нравится её вкус.

This also means Although the brynza is salty, I still like its taste.

The difference is mainly in tone:

• хотя = straightforward although
• пусть = more like granted, even if, let it be so

So пусть can sound a little more rhetorical or conversational, as if the speaker is acknowledging an objection before continuing.

Because the first part is a subordinate concessive clause:

• Пусть брынза и солёная, ...

and the second part is the main clause:

• мне всё равно нравится её вкус

Russian separates these with a comma, just like English usually does with although/even though clauses.

So the structure is:

• Even though X, Y.

That is why the comma is required here.

Yes, exactly. That is one of the main nuances of this sentence.

It does not just state two facts. It presents:

1. a possible objection: the brynza is salty
2. the speaker’s unchanged opinion: I still like its taste

So the overall feeling is:

• Sure, it’s salty, but I still like how it tastes.
• Granted, the cheese is salty, but I like its taste anyway.

That concessive contrast is created by the combination of:

• пусть
• и
• всё равно
