Min niece kan godt lide rosiner og nødder, så hun vil også have lidt vanilje i dejen.

Because niece is a common-gender singular noun in Danish.

Danish possessives match the gender/number of the noun:

• min = common gender singular
• mit = neuter singular
• mine = plural

So you get:

• min niece = my niece
• mit hus = my house
• mine nødder = my nuts

It means like.

This is one of the most common Danish ways to express liking something:

• Jeg kan lide kaffe = I like coffee
• Jeg kan godt lide kaffe = I like coffee

In everyday Danish, kan godt lide is extremely common and very natural.

On its own, godt often means well, fine, or good. But in kan godt lide, it is part of a very common idiomatic expression. You usually should not translate it word for word here.

So kan godt lide is best understood as a whole chunk meaning like.

Because Danish, like English, often uses bare plural nouns when talking about things in general.

So:

• rosiner = raisins
• nødder = nuts

This does not mean the raisins or the nuts. It just means raisins and nuts in a general sense.

If you wanted specific ones, you could say:

• rosinerne = the raisins
• nødderne = the nuts

Here så means so.

It introduces the result or consequence of the first clause:

• She likes raisins and nuts, so she also wants a little vanilla in the dough.

It links the two ideas together very naturally.

Because Danish main clauses usually place the finite verb early, and words like også usually come after that finite verb.

So the normal order is:

• hun vil også have ...

not:

• hun også vil have ...

This is a very important Danish word-order pattern.

Here it means wants or would like to have.

Danish vil can express:

• future meaning
• intention
• desire

In this sentence, it is about desire:

• hun vil også have lidt vanilje = she also wants a little vanilla

So you should not read it as simple future English will have here.

Lidt means a little, a bit, or some.

Here it goes with vanilje, which is an uncountable ingredient:

• lidt vanilje = a little vanilla / some vanilla

You will see lidt very often with mass nouns:

• lidt sukker = a little sugar
• lidt vand = a little water

Because vanilje is being used as a mass noun here, meaning the ingredient in general, not one separate countable item.

After lidt, Danish normally uses the noun without an article:

• lidt vanilje
• lidt sukker
• lidt mel

So en vanilje would not fit this context.

Because dejen is the definite form of dej:

• en dej = a dough / a batter
• dejen = the dough / the batter

The sentence is talking about a specific dough or batter that is already understood from the situation, so Danish uses the definite form dejen.

It can mean either, depending on context.

In cooking and baking, Danish dej is often the mixture you are preparing. In English, the best translation may be dough or batter, depending on how thick it is and what you are making.

Because Danish normally uses a comma to separate two full clauses.

Here you have:

• Min niece kan godt lide rosiner og nødder
• så hun vil også have lidt vanilje i dejen

Each part has its own verb, so the comma helps mark the boundary between the two clauses.
