I have several quite odd concoctions on the liquor shelf. Several made by me (not in a distilled way as that is both illegal & dangerous) including Earl grey gin, Blueberry vodka, Blackberry gin & Damson brandy.
I also have several manufactured oddities too. St Germain elderflower liqueur, very handy in a number of gin & champagne confections. Creme de violette which makes the fabulous "Arsenic & old lace". Maraschino a bit part player in several very good drinks. Qi black tea liqueur a lovely smokey brew. Then there is the small bottle of celery bitters, which is why I'm writing this.
Fentimans make lovely non-alcoholic drinks, their Curiosity Cola is a favourite. Today though my Fentimans supplier had a groovy little box of tonic waters. Now I fully expected this to be a really full on bitter tonic, I wasn't off the mark, the quinine note is right upfront, a great tonic. Which of course requires a great mix to fully appreciate. I give you the garden tonic.
Large measure of Gin (always a good start)
1/2 measure marschino
dashes of celery bitters (2-3 depending on taste)
top of with tonic
A strong bitter grown up drink, excellent long drink, I heartily recommend it.
