Here is the recipe for my favourite akvavit. I originally found this recipe on the web in Swedish and will now try to translate it for you. It's a copy of the brand Falu Brännvin that is no longer made.
It's both sweet and a little bit bitter and with elegant anise and citrus flavour.
Pour 70 cl (1.5 pints) of your finest 40% ABV neutral in a one litre container with a pretty big opening.
*1 tsp whole caraway
*1 tsp whole fennel
*1 whole star anise
*15 g (.5 oz ) of bitter orange peels
Let macerate for a week and the filter it.
Add 1 dl (7 tbsp) sugar and let i melt.
Now add some more neutral. This is a question of how strong flavour you like but I add about 25 cl (.5 pint) or so.
To add some body and sourness add 4 cl (8 tsp) full bodied Scotch and the juice from half a lemon.
It's ready to drink right away but the taste gets better if it's allowed to rest for a while.
