Hola David,

Remember that this is all about what you want to say, and how to say it.

For the sake of completeness I would make a small change.

Something “reminds me of” OR “is similar to”: Do not omit the “a” [from Recordar + a]

Something “is brought to mind”: Omit the “a” [from Recordar + a].

Something reminds me that: Use Recordar + que

Using “lo que” for what.

Think of “lo que” as meaning “what, which, that which, or the thing that. It is used in reference to an idea that is expressed in the same sentence. If you look at the sentence “This reminds me of what happened last month” you will see that the “what” is referring to “what happened last month.” You could substitute “that which and “the thing that” in the sentence and it would still make sense. Hence lo que. 

There is a lesson in B1 which says more about this.Here is the link:

Using lo que = what, which, that which, the thing that (relative pronouns)

Saludos. John

Trying again with that link.
