Der Brei ist noch zu heiß, also puste ich darauf und stelle die Schüssel kurz ans Fenster.

Brei is a masculine noun in German, so its basic article is der.

• der Brei = the porridge / the mush / the cereal
• In the nominative singular, masculine nouns normally use der

Here, Der Brei is the subject of the sentence, so nominative is exactly what you expect.

Here noch means still.

So:

• zu heiß = too hot
• noch zu heiß = still too hot

It suggests that the porridge has probably been cooling for a while, but it has not cooled enough yet.

Compare:

• Der Brei ist zu heiß. = The porridge is too hot.
• Der Brei ist noch zu heiß. = The porridge is still too hot.

Because zu means too in the sense of more than is acceptable or suitable.

• heiß = hot
• zu heiß = too hot

So Der Brei ist noch zu heiß does not just describe temperature; it implies a problem: it is too hot to eat comfortably.

This is the same pattern as:

• zu kalt = too cold
• zu schnell = too fast
• zu laut = too loud

Because also takes the first position in the clause, and German main clauses still keep the finite verb in second position.

So the structure is:

• also = position 1
• puste = position 2
• ich = then the subject comes after the verb

That gives:

• also puste ich darauf

A useful way to think about it is: German does not mean “verb second after the subject”; it means verb second in the clause.

You see the same pattern in sentences like:

• Dann gehe ich nach Hause.
• Heute habe ich keine Zeit.
• Deshalb bleibt er hier.

No. German also usually means so, therefore, or well then, not English also meaning in addition.

In this sentence:

• Der Brei ist noch zu heiß, also puste ich darauf ...
• = The porridge is still too hot, so I blow on it ...

If you want English also in the sense of too / as well, German usually uses words like:

• auch
• sometimes ebenfalls

So this is a very common false friend.

Because German often uses a da-compound for things or ideas after a preposition.

The verb is:

• auf etwas pusten = to blow on something

When the “something” is a thing, German very naturally replaces auf + it with darauf:

• Ich puste auf den Brei.
• Ich puste darauf.

This is much more natural than auf ihn / auf es here.

A good rule: for non-personal things, German often prefers forms like:

• darauf = on it
• damit = with it
• davon = of it / from it
• dafür = for it

For people, you usually use the normal preposition + pronoun:

• auf ihn
• mit ihr
• für sie

Because the subject ich is already understood and shared by both verbs.

So:

• also puste ich darauf und stelle die Schüssel kurz ans Fenster

means:

• ... so I blow on it and put the bowl by the window for a moment

German often leaves out the repeated subject in coordinated structures when the same person is doing both actions.

You could say:

• ... also puste ich darauf und ich stelle die Schüssel kurz ans Fenster.

But that sounds heavier and less natural in this context.

German often chooses placement verbs more specifically than English does.

• stellen = to put something in an upright / standing position
• legen = to lay something down
• setzen = to set/place something into a sitting position, or to seat someone

A bowl is normally understood as something that is placed upright on its base, so stellen is the natural choice:

• die Schüssel ans Fenster stellen

In English, we often just say put, but German is more specific here.

It is accusative, because it is the direct object of stelle.

The noun is:

• die Schüssel = the bowl

This noun is feminine, and feminine singular looks the same in nominative and accusative:

• nominative: die Schüssel
• accusative: die Schüssel

So even though the form does not change, the function does: it is the thing being moved/placed.

ans is a contraction of an das.

• an das Fenster → ans Fenster

Here, an is a two-way preposition, so the case depends on whether there is movement/change of position or just location.

In this sentence there is placement/movement:

• ich stelle die Schüssel ans Fenster
• I put the bowl to/by the window

So German uses accusative.

If the bowl were already there and you were only describing its location, you would use dative:

• Die Schüssel steht am Fenster.
• The bowl is by the window.

So:

• ans Fenster = toward / to the window area, with placement
• am Fenster = at/by the window, location only

Not necessarily. Very often it just means by the window or up to the window area.

German an can be broader than English against. In everyday usage here, it usually means putting the bowl near the window so it cools faster, not pressing it onto the glass.

So the natural English idea is:

• put the bowl by the window

rather than a very literal:

• put the bowl onto/against the window

Here kurz means briefly or for a short time.

So:

• stelle die Schüssel kurz ans Fenster
• = put the bowl by the window for a moment

It tells you the action or result is temporary.

German often uses kurz this way with everyday actions:

• Ich warte kurz. = I’ll wait a moment.
• Ich gehe kurz raus. = I’m stepping out briefly.
• Stell es kurz hierhin. = Put it here for a moment.

Yes, often you can, but pusten is especially common in everyday speech for blowing air gently, such as onto hot food.

• pusten = blow, puff
• blasen = blow

In this context, pusten sounds very natural and conversational.

For example:

• Ich puste auf den Brei.
• Ich blase auf den Brei.

Both are understandable, but pusten often feels a bit more idiomatic for cooling food.

Yes. Here also introduces a new main clause, so the comma is correct.

The sentence has this structure:

• Der Brei ist noch zu heiß,
• also puste ich darauf und stelle die Schüssel kurz ans Fenster.

German punctuation regularly separates main clauses like this, especially when the second one is introduced by a connector such as also.
