Whiskey Balls - Recipe from my Grandma

I had never made these before, but thought it would be fun to give it a try.  As I was making these, I imagined my Grandma rolling these between her own fingers days before Christmas preparing yummy treats for everyone.  I hear she was a great cook, however, I didn't get to know that side of her very much since we rarely saw them, and she died during my first year of college.  However, she did leave a whole bunch of really yummy recipes!  Here's one of them by request...

Whiskey Balls
2 boxes powdered sugar
1 quart chopped pecans (finely chopped)
1 can sweetened condensed milk
3 Tablespoons Whiskey / Bourbon (I used Southern Comfort)

1/2 brick parafin wax
2 bags semi sweet morsels

Directions:
Mix first 4 ingredients with electric mixer and refrigerate for 2 - 24 hrs.
Roll into 1 inch balls and refrigerate again till hardened again.
In a double broiler, melt chocolate chips and wax (being very careful not to get any water in the chocolate...if you do the chocolate will be no good...it will harden and you will have to throw it out)
Then with tongs, or a fork, dip balls in chocolate and cool on wax paper.  To speed up the cooling, you can put them in the refrigerator.
Makes about 4-5 cookie sheets jam packed full.
Enjoy!!

PS...I actually halved the recipe and it was plenty!
