Bu kadar lezzetli bir çorbanın tarifini sormadan edemiyorum.

Bu kadar literally means this much or to this degree, but in sentences like this it often works like so in English.

So bu kadar lezzetli means so delicious or this delicious. It intensifies lezzetli.

Here bir helps create the sense of such a delicious soup or a soup this delicious.

Turkish often uses bir in descriptive phrases like this:

• güzel bir ev = a beautiful house
• bu kadar güzel bir ev = such a beautiful house

So bu kadar lezzetli bir çorbanın is not strange at all. It sounds natural and matches the English idea of such a delicious soup.

Because the sentence is using a possessive construction: the recipe of the soup.

In Turkish, that structure is:

• possessor + -ın / -in / -un / -ün
• possessed noun + possessive ending

So:

• çorba = soup
• çorbanın = of the soup / the soup’s

That is why you get çorbanın tarifi = the soup’s recipe or the recipe of the soup.

Because it contains more than one grammatical piece:

• tarif = recipe
• tarifi = its recipe / the recipe
• tarifini = its recipe as a specific direct object

In çorbanın tarifini:

• -i shows that tarif belongs to çorba
• the final accusative ending marks it as the object of sormak
• the n is a buffer consonant between those endings

So tarifini sormak means to ask for its recipe.

This is an important distinction.

• çorba tarifi = a soup recipe / recipe for soup in general
• çorbanın tarifi = the recipe of this specific soup

In this sentence, the speaker is reacting to one particular soup they are tasting. That is why çorbanın tarifini is the better choice.

This is a very common Turkish pattern:

-madan / -meden edememek

It means cannot help doing, cannot resist doing, or just have to do.

So:

• sormadan edemiyorum literally looks like I can’t do without asking
• but idiomatically it means I can’t help asking

This is a fixed expression, so it is best learned as a whole pattern.

Because this is an idiomatic structure, not a simple double negative.

• sormadan = without asking
• edemiyorum = I can’t do

Together, they form the pattern -madan edememek, which means to be unable to refrain from doing something.

So you should not read it as two separate negatives that cancel each other out. It is one set expression.

It comes from etmek, which usually means to do or to make.

But in this pattern, etmek is not carrying its full everyday meaning by itself. It is part of the fixed expression -madan edememek.

So in this sentence, edemiyorum is functioning more like a grammatical support verb inside the idiom, not like a full literal do.

Yes, both are possible in some situations, but they are not exactly the same.

• tarifini sormak = to ask for the recipe
• tarifini istemek = to request the recipe

Sormak focuses on the act of asking.
İstemek focuses more on wanting or requesting.

In this sentence, sormak sounds very natural because the speaker feels compelled to ask.

Yes. It is very natural Turkish word order.

Turkish usually puts the main verb at the end, so the long object phrase comes first:

• Bu kadar lezzetli bir çorbanın tarifini = the recipe of such a delicious soup
• sormadan edemiyorum = I can’t help asking

So the sentence builds up the object first and finishes with the verbal idea at the end, which is typical in Turkish.

Yes:

• Bu kadar = this much / so
• lezzetli = delicious
• bir = a / such a
• çorbanın = of the soup / the soup’s
• tarifini = its recipe, as the direct object
• sormadan = without asking
• edemiyorum = I can’t do it / I can’t help it

As a whole, the key chunk to recognize is:

• tarifini sormak = to ask for its recipe
• sormadan edemiyorum = I can’t help asking

So the sentence is built from a noun phrase plus a very common idiomatic verb pattern.
