This recipe creates a wonderful thick blackcurrant liqueur, there are no exact amounts in the recipe as that all depends on how many fresh blackcurrants you have. It can be drunk in small quantities or served with dry white wine, sparkling wine or over vanilla ice cream.
I agree, why would you boil off the alcohol? What I have done is drain and sieve the blackcurrent steeped alcohol and put it back in the jar for now. Put the blackcurrents in the processor and whizzed it. Then cooked the blackcurrent mash down till is soft, I did not boil this. Sieve the mash then filter.I used an old T Shirt, clean of course, this is much more effective than a coffee filter. The resulting liquid is put back in the rinsed pan with the sugar, stir until dissolved. Do not boil, mixture was warm. Cool then add the extra alcohol and the original steeped alcohol. Stir and bottle. I do sterilize my bottles as I would for anything I was brewing to remove unwanted bacteria. - 09 Dec 2013 (Review from Allrecipes UK & Ireland)
4. if you boil it, you boil the alcohol off :-( maybe slightly warmed, to help dissolve the sugar, but not really necessary. it just takes longer. (maybe put it in a jar / bottle & keep shaking to dissolve) 5. clean bottle, yes, sterillised, hot? why ? that's the whole point of the alcohol, (this isn't jam y'know) - 23 Sep 2013 (Review from Allrecipes UK & Ireland)
The Vodka extracts the flavour from the berries and provides Alcohol for the finished product. Boiling it removes up to 85% of the Acohol. Do not boil it unless you want it ruined. Simply filter the Berry/ Currant and Vodka mixture to get the solids out and then add a simple syrup (Sugar disolved in Water) do not heat it. Blend together by shaking in a Bottle or Mason Jar. Delicious! - 04 Aug 2017 (Review from Allrecipes UK & Ireland)
