Learn Hardcore Spanish (Spain): Buscamos un tipo de pan menos salado y un poco más dulce. - We are looking for a type of bread that is less salty and a bit sweeter.

Buscamos clearly shows 1st person plural (we).
Adding nosotros is only needed for emphasis or contrast:
- Nosotros buscamos un tipo de pan… (We – not someone else – are looking for a type of bread…)

So the sentence without nosotros is the normal, neutral version.

How do I know whether buscamos is present tense (we look for / we are looking for) or past tense (we looked for)?

Buscamos has the same form in:

Present indicative: nosotros buscamos = we look for / we are looking for
Preterite (simple past): nosotros buscamos = we looked for

You know the time from context or time expressions:

Ahora buscamos… → present: we are looking for…
Ayer buscamos… → past: yesterday we looked for…

In your sentence, with no past-time marker and a shopping-like context, it’s naturally understood as present.

Could I say Estamos buscando un tipo de pan… instead of Buscamos…? What’s the difference?

Yes, both are correct, but they feel slightly different:

Buscamos un tipo de pan…
- Simple present.
- Can sound like a general intention or current action, depending on context.
- In everyday speech when shopping, this is completely normal: like saying We’re looking for….
Estamos buscando un tipo de pan…
- Present progressive (we are currently in the process of searching).
- Emphasizes the action happening right now.

In many real-life situations (e.g. speaking to a shop assistant), Spaniards would naturally say Buscamos….

Why is it un tipo de pan and not something like un tipo de panes?

With the structure un tipo de + noun, the noun is usually in the singular to refer to a kind/category:

un tipo de pan = a type of bread
un tipo de queso = a type of cheese

You’re not counting individual items here, but describing a kind.
You could say tipos de panes (types of breads) in some contexts, but for “a type of bread” the natural phrase is un tipo de pan.

Should salado agree with tipo (feminine/masculine), or with pan? Why is it salado and not salada?

The adjective salado agrees with the noun it is describing:

un tipo de pan menos salado → the adjective refers to pan (masculine, singular), so salado is correct.

Even though tipo is masculine, the phrase de pan narrows down what type it is, and semantically salado is talking about the bread, not about the type.

Same with más dulce: it describes the bread.

Why is salado placed after pan? Could I say un tipo de pan salado with salado before?

In Spanish, most adjectives normally go after the noun:

pan salado (salty bread)
café caliente (hot coffee)

You can put some adjectives before the noun, but that often changes the nuance or feels poetic/unusual.

For a neutral description (less salty, a bit sweeter), the standard and most natural order is noun + adjective:
un tipo de pan menos salado y un poco más dulce.

What does menos salado literally mean, and is something being compared even if it’s not stated?

Menos salado literally means less salty. It’s a comparative form:

salado = salty
menos salado = less salty

Even if you don’t say what you’re comparing with, Spanish (like English) allows the comparison to be understood from context:

Buscamos un tipo de pan menos salado…
→ less salty than the bread we usually buy / than this bread / than what we had before, etc.

The “than …” part is implied, just like in English.

Why is it un poco más dulce and not un poco de más dulce or something similar?

Here, un poco acts as an adverbial phrase meaning a little / a bit and modifies the comparative más dulce:

dulce = sweet
más dulce = sweeter
un poco más dulce = a little / a bit sweeter

You only use de after un poco when it’s followed by a noun:

un poco de pan (a bit of bread)
un poco de agua (a bit of water)

But with adjectives, no de:

un poco más dulce, un poco más salado, un poco caro.

What’s the difference between un poco más dulce and algo más dulce?

Both are possible and close in meaning:

un poco más dulce
- Very common and neutral.
- Suggests a small increase in sweetness: a little bit sweeter.
algo más dulce
- Also used, but a bit less frequent in this type of everyday phrase.
- Can feel slightly more formal or vague: somewhat / rather sweeter.

In a shop context, Spaniards would more naturally say un poco más dulce.

Why is it Buscamos and not something like Miramos para (literally “we look for”)?

In Spanish, buscar already means to look for / to search for. You don’t add a preposition:

buscar algo = to look for something
- Buscamos un tipo de pan… = We are looking for a type of bread…

If you said mirar para, it would be incorrect in this sense.
Mirar is just to look at:

Miramos el pan = We look at the bread.

Is pan countable in Spanish? When would you say un pan instead of just pan?

Pan works mostly like an uncountable noun (bread) in general references:

Comemos pan todos los días. = We eat bread every day.
Buscamos un tipo de pan… = We’re looking for a type of bread…

But in some contexts you’ll hear un pan, often meaning a loaf / a piece of bread, especially with specific types:

un pan integral = a wholemeal loaf
tres panes = three loaves of bread (e.g. from the bakery)

In your sentence, you’re talking about a kind of bread, so plain pan (without article) is the natural choice.

Could I use queremos instead of buscamos, like Queremos un tipo de pan menos salado…?

Yes, but the meaning shifts slightly:

Buscamos un tipo de pan…
- Focuses on the action of looking/searching, especially natural if you’re in a shop asking for help.
Queremos un tipo de pan…
- Focuses on desire/want: we want a type of bread that is less salty and a bit sweeter.

Both are correct; in a bakery or supermarket in Spain, you could use either.
If you’re literally asking someone to help you find it, Buscamos… sounds especially appropriate.
