Flavoring Vodka

[winestill]

Hey guys.

I was wondering how you would make clear vodka
with flavors like in Absolut series,
f.ex. Absolut Apeach or Vanilla.
Do I first put it in a jar with the fruit and fill it to
the top of the fruit and put sugar and so on and boil
or would I mash the fruit and then put it in
the boiler with 30-40% vodka and distill it that way?

Or is there another way?

And I forgot. What would the recipe be? Let's have it
it 1L of 40%
