parts of speech - I am looking forward to ....? (followed by a Gerund)?

I know, that

I am looking forward to hearing from you.

is correct.
But I am not sure, if this holds also for other verbs?

So is

I am looking forward to taste your cookies.

or is

I am looking forward to tasting your cookies.

correct?

Answer

It is indeed. In each case, you need an object, so you need a noun or noun phrase:

I am looking forward to the holidays.

So in order to make a verb serve you must use the gerund.

I am looking forward to taking some time off.
