My family has been making this every winter for about 30 years. It's made from actual snow from the ground. We had our first snow today and I made some and taught my niece the recipe. it turned out GREAT.
About 12 cups of good fresh snow
1 12 ounce can of condensed milk
1 cup confectioners sugar
1 tablespoons of Almond extract
2 tablespoons of Rum flavor
3 tablespoons of Vanilla extract
a few dashes of pumpkin pie spice
In your bowl full of snow fold in the sugar, vanilla, rum and almond.
pour the milk in, stir until mixed all together. the snow should melt down at this point to about half the amount you started with. (which is why you need so much to start)
stir in the pumpkin pie spice.
Cover the bowl, sit in freezer for about 20 minutes.
then have at it!
