Remove hyphens and replace them with spaces and write in liquid

Using fluid, I use product tags to create page titles. I want page titles to be free of hyphens and every headword.

Example:

If the tag (used to create the title) is “potato chips”. I want the name to be Potato Chips.

If I use:

{{current_tags.first}}

It generates the title "potato chips."

If I use:

{{current_tags.first | replace: '-', ' '}}

It generates the heading for "potato chips."

If i use

{{current_tags.first | replace: '-', ' ' | capitalize}}

we get the name "potato chips."

If anyone knows how I can get the heading "Potato Chips", that would be great.
