Hi perroloko,
You'll want to throw some fennel seeds in that mix and go easy on the nutmeg or it will overpower the other herbs.
The traditional recipes macerate the initial herbs for 12 to 24 hours in 85% neutral then dilute and pot still until the output becomes cloudy or you have collected the same volume as the initial pre-diluted charge. In my experience by the time that happens you're in tail country and they are not too tasty although this could be due to my small batch size. I always do cuts on my absinthe and select the jars that smell and taste the best - FWIW my blanche has been compared very favourably to the higher and commercial offerings.
As a starting point, have a look at the historical recipe section over at
www.feeverte.net for basic details on the ingredients and procedure. Scale the recipes down for the volume of neutral you want to use.
Be sure to keep your macerated herbs away from the elements of they will scorch and ruin your day for sure. I strain the herbs into a hops bag and suspend it just above the liquid in the boiler.
Cheers,
Prof. Green.
