How to make a homemade Phrostie?
I take it you're a fellow NY'er :) 

The classic Phrostie consists of just 4 ingredients: Kool-aid mix, sugar, water and Everclear. First, mix the Kool-aid, sugar and water until everything is dissolved. You want to use about 1/2 to 1/3 the amount of water that you would normally use and the rest (1/2 or 2/3) would be Everclear. 

Here's my Phrostie interpretation (uses 1/2 everclear and 1/2 water):


3 (6g) packages Kool-Aid, your favourite flavour
1 3/4 cups sugar
8 cups cold water
8 cups Everclear


This should make a little more than a gallon total. Portion it out in capped bottles, then put them in the freezer for a few hours. 

I've also poked around with a "fancy" Phrostie:


3 cups Marino's Italian Ices
8 oz Brugal Anejo
5 oz Brugal Especial Extra Dry Silver
1 can frozen pineapple juice concentrate
1 can frozen orange juice concentrate 
8 oz grenadine syrup
