Hacemos el plegado durante la fermentación en bloque.

Hacemos is the 1st person plural present tense of hacer, so it means we do or we make.

• hacer = the infinitive, to do / to make
• haciendo = the gerund, doing / making
• hacemos = we do / we make

So the sentence is talking about what we do as a general action or instruction.

Spanish often leaves out subject pronouns when they are clear from the verb ending.

• hacemos already tells you the subject is we
• So nosotros hacemos is possible, but usually unnecessary

Spanish is a pro-drop language, so this is very normal. Adding nosotros would only be for emphasis or contrast.

Here, hacemos is best understood as we do or we carry out.

In baking language, hacer el plegado means to do the fold / perform the folding step. English often uses a more natural verb such as fold, but Spanish commonly uses hacer with many actions:

• hacer una pausa = take a break
• hacer ejercicio = exercise
• hacer el plegado = do the folding step

So this is a very natural Spanish structure.

Because plegado is being used here as a noun, not just as a past participle or adjective.

• plegar = to fold
• el plegado = the folding, the fold, the folding step/process

Spanish often uses the definite article with action nouns:

• el amasado = kneading
• el horneado = baking
• el plegado = folding

So hacer el plegado means to do the folding.

In this sentence, plegado is a masculine singular noun.

It comes from the verb plegar, but here it is functioning as the name of a process or step. This is common in technical, culinary, and instructional Spanish.

So grammatically:

• plegar = verb
• plegado = noun meaning folding or folding step

It is not acting like an adjective here.

Durante means during, so it clearly tells us that the folding happens in the course of that stage.

• durante la fermentación = during fermentation

Using en would not express the same thing as naturally. En often means in, on, or at, but here the idea is specifically during the time of fermentation, so durante is the right choice.

In bread-making, fermentación en bloque means bulk fermentation.

Literally, en bloque means something like as one mass or in one piece/block. It refers to the stage when the dough ferments before being divided into individual pieces.

So:

• fermentación = fermentation
• fermentación en bloque = bulk fermentation

This is a technical baking expression.

Because nouns in Spanish have grammatical gender, and these two nouns have different genders:

• la fermentación = feminine
• el plegado = masculine

That is why the articles are different:

• la for feminine singular
• el for masculine singular

There is no special rule here that links the two words; you just learn each noun with its article.

The accent mark shows where the stress goes: fermentaCIÓN.

Without the accent, Spanish pronunciation rules would suggest a different stress pattern. The written accent makes the pronunciation clear and correct.

This is very common with nouns ending in -ción:

• fermentación
• nación
• información

These words are typically stressed on the final syllable before -n because of the accent mark.

Yes, it is in the present tense.

Here the present can be understood in a few natural ways, depending on context:

• instructional present: as in a recipe or process description
• habitual present: this is what we normally do
• general present: this is the standard procedure

So Hacemos el plegado durante la fermentación en bloque could mean:

• We do the folding during bulk fermentation
• We perform the fold during bulk fermentation
• In a recipe context, even The folding is done during bulk fermentation

Yes, absolutely. Plegamos durante la fermentación en bloque is also grammatical and natural.

The difference is mainly one of expression:

• Hacemos el plegado = we do the folding, we carry out the folding step
• Plegamos = we fold

The version with hacer + noun can sound a bit more procedural or technical, which fits recipe and process language well.

The structure is:

• Hacemos = verb
• el plegado = direct object
• durante la fermentación en bloque = time phrase / prepositional phrase

So the sentence follows a very common Spanish order:

Verb + object + time expression

Spanish word order is flexible, but this order is completely normal and natural here.
