Comparamos la harina de fuerza con la harina integral.

Comparamos is the present indicative form of comparar for nosotros/nosotras: we compare.

So the sentence literally has we compare. In Spanish, this can be used:

• literally: We compare...
• in instructional or explanatory language: We compare... / Let’s compare...

Without more context, comparamos is simply the normal we compare form.

Spanish often omits subject pronouns because the verb ending already tells you who the subject is.

• comparo = I compare
• comparas = you compare
• comparamos = we compare

Because -amos clearly shows we, Spanish usually leaves out nosotros unless the speaker wants emphasis or contrast.

So:

• Comparamos la harina... = normal
• Nosotros comparamos la harina... = more emphatic, like we compare...

Yes, it can. In Spanish, the nosotros form of some -ar verbs is the same in:

• the present: we compare
• the preterite: we compared

So comparamos can mean either:

• we compare
• we compared

You tell which one is meant from the context.

In your sentence, it most naturally sounds like present tense unless the surrounding text clearly refers to a completed past action.

Spanish often uses the definite article more than English does.

Here, la harina means the flour. Even if English might sometimes say just flour, Spanish commonly uses the article when talking about a specific type or category in a sentence like this.

So:

• la harina de fuerza = the strong flour / bread flour
• la harina integral = the wholemeal flour / whole wheat flour

Because Spanish normally uses an article with each noun phrase.

So:

• la harina de fuerza
• la harina integral

This is more natural than trying to share one article across both items. Repeating la makes it clear that you are comparing one type of flour with another type of flour.

Literally, de fuerza means of strength, but that is not how you would normally translate it in natural English.

In Spanish baking vocabulary, harina de fuerza refers to flour with higher protein/gluten strength, used especially for bread and similar doughs. In English, this is often rendered as:

• strong flour
• bread flour
• sometimes high-protein flour

So this is a fixed expression in the context of flour.

Spanish often uses noun + de + noun structures where English might use:

• an adjective
• a compound noun
• a more specialized term

So harina de fuerza is just the standard way to name that type of flour. You should learn it as a set phrase rather than trying to build it word-by-word.

In food vocabulary, integral means wholegrain/wholemeal/whole wheat, depending on the product and the variety of English.

So harina integral is:

• wholemeal flour in much British English
• whole wheat flour in much American English

It does not mean integral flour in normal English.

Because comparar is commonly used with con when you compare one thing with another:

• comparar X con Y = to compare X with Y

So:

• Comparamos la harina de fuerza con la harina integral.
• We compare bread flour with wholemeal flour.

You may also sometimes see comparar X y Y without con, but comparar ... con ... is extremely common and very standard.

Sometimes Spanish allows comparar algo a algo, but that often leans more toward likening one thing to another, depending on the context and style.

For straightforward comparison of two items, comparar X con Y is the most natural choice here.

So in this sentence, con is exactly what a learner should expect.

In Spanish, most descriptive adjectives usually come after the noun.

So:

• harina integral not
• integral harina

This is one of the basic word-order differences between Spanish and English. English often puts modifiers before the noun; Spanish often places them after it.

In standard Spanish, the h is silent.

So harina is pronounced roughly like:

• a-REE-na

Not like English harina with an h sound.

A few useful pronunciation points:

• fu sounds roughly like fwe
• er in Spanish has a tapped/flapped r
• z in Spain is pronounced like th in think

So in Spain, fuerza sounds approximately like:

• FWEHR-tha

In much of Latin America, the z sounds like s, so it would be closer to:

• FWEHR-sa

Since you asked about Spanish from Spain, the th sound is the one to expect.

Yes. It is a natural, standard sentence in Spanish from Spain.

The vocabulary especially fits well in a cooking or baking context:

• harina de fuerza is a very common Spain-Spanish term
• harina integral is also standard

So the sentence sounds like normal explanatory language, such as in a recipe, lesson, or comparison of ingredients.
