Psst! Want to have one of the best liqueurs ever? You can make it yourself! Warning: you won't be able to look at those other fake fruit essence vodkas the same again. This Ruby Red Grapefruit Liqueur recipe is like a Greyhound that's been reduced into a liqueur. It gets smoother with age so feel free to age it in the freezer for up to two years.

4 organic Ruby Red grapefruits
750ml vodka (about one bottle)
¼ cup white sugar

1)
Zest the grapefruits and put the zest into a ½ gallon glass container. Add the vodka to the container. Using organic grapefruits is important because non organic grapefruit rinds have lots of pesticide residues.



2)
Cut the grapefruits in half, juice them and pour the juice in the colander to filter out the pulp. This should give you about 1 ¾ cups of grapefruit juice but possibly more depending on their size.



3)
Transfer no more than 2¼ cups of the juice to a medium sized saucepan. Whisk in ¼ cup sugar on medium heat until it's dissolved. 

4)
Add the juice to the ½ gallon glass container, close the lid tightly and give it a shake. 

Keep in a cool dark place and strain out the grapefruit zest after two weeks. This can be done by using a cotton coffee filter placed in a funnel that is placed over a bottle. Age at least two more weeks. Store the bottle in the freezer.
