Prije nego što dodaš brašno, umuti jaja.

It means before in the sense of before someone does something.

So:

• Prije nego što dodaš brašno = Before you add the flour

This is a very common Croatian way to introduce a clause with a verb after before.

A rough pattern is:

• prije nego što + verb

For example:

• Prije nego što odeš, nazovi me. = Before you leave, call me.

In Croatian, prije nego što is a fixed expression meaning before when it introduces a whole clause.

So the sentence is built like this:

• prije nego što = before
• dodaš brašno = you add the flour

You will often see the full form prije nego što in standard Croatian.

In less formal speech, people may sometimes shorten it to:

• prije nego dodaš brašno

But prije nego što is the safest form for learners.

Because Croatian uses a finite verb after prije nego što.

English can say:

• Before adding the flour...
• Before you add the flour...

Croatian normally prefers the second type here:

• Prije nego što dodaš brašno...

So instead of using an -ing form like English often does, Croatian usually uses a full clause with a conjugated verb.

This is very normal in Croatian.

After expressions like prije nego što, Croatian often uses the present tense form to talk about a future action relative to another action.

So:

• Prije nego što dodaš brašno, umuti jaja.

does not mean the flour is being added right now. It means:

• Before you add the flour, beat the eggs.

So the present form dodaš is being used for a future event in a subordinate clause.

Dodaš is 2nd person singular present tense, meaning you add.

It matches the command in the main clause:

• umuti = beat!
• implied subject = you

So the whole sentence is talking to one person informally:

• Before you add the flour, beat the eggs.

If you were addressing more than one person, or using formal Vi, the form would change:

• Prije nego što dodate brašno, umutite jaja.

Because umuti is the imperative of umutiti, which means to beat/whisk until combined or fluffy, especially in cooking.

This verb is perfective, so it focuses on completing the action.

Compare:

• mutiti = to be beating / to beat in a more ongoing sense
• umutiti = to beat up / whisk thoroughly / beat until done

In a recipe, Croatian often prefers the perfective verb because the instruction is about finishing the step:

• umuti jaja = beat the eggs

Yes. Dodati is generally perfective and means to add as a completed action.

So in this sentence:

• dodaš brašno = you add the flour as one completed step

That fits recipe language very well, because recipes often describe actions step by step as completed tasks.

A related imperfective verb is:

• dodavati = to be adding / to add repeatedly

But that would not sound as natural here.

Because the sentence begins with a subordinate clause:

• Prije nego što dodaš brašno, = dependent clause
• umuti jaja. = main clause

Croatian normally separates this kind of introductory clause with a comma, just like English often does:

• Before you add the flour, beat the eggs.

So the comma is expected here.

Both are in the accusative case, because they are direct objects.

• dodati brašno = to add flour
• umutiti jaja = to beat eggs

In this sentence, the forms happen to look like the dictionary forms:

• brašno is neuter singular, and its accusative is the same as its nominative
• jaja is plural, and here the accusative looks the same as the nominative plural

So even though the forms do not change visibly here, they are still functioning as accusatives.

Because Croatian has no articles like English a/an/the.

So:

• brašno can mean flour or the flour
• jaja can mean eggs or the eggs

You understand the exact meaning from context. In a recipe, it often naturally means the specific ingredients being used.

Yes, Croatian word order is fairly flexible, but this version is the most natural and neutral for a recipe instruction:

• Prije nego što dodaš brašno, umuti jaja.

You could move things around for emphasis, but learners should stick to this order.

For example, the main instruction first would be less natural in this context:

• Umuti jaja prije nego što dodaš brašno.

This is still correct, but the original version sounds more like a standard recipe step.

It is informal singular, because it uses:

• dodaš
• umuti

These are forms used when speaking to one person with ti.

In recipes, Croatian often uses this informal singular imperative, similar to English recipe instructions.

A more formal or plural version would be:

• Prije nego što dodate brašno, umutite jaja.

That could mean either:

• speaking politely to one person, or
• speaking to several people

Yes, Croatian can sometimes use a noun phrase, for example:

• Prije dodavanja brašna, umuti jaja.

This means roughly:

• Before adding the flour, beat the eggs.

But for learners, prije nego što + verb is usually easier and more common to understand clearly:

• Prije nego što dodaš brašno, umuti jaja.

That version is very natural and straightforward.
