Large bowl of clean snow (my bowl is 16 cup capacity)
1 teaspoon vanilla
1 can evaporated milk (12 ounces)
¾ cup sugar

Pour vanilla and sugar over snow. Start adding the milk, mixing on low until all is incorporated and slushy. Cover and put into the freezer for at least one hour before eating or until firm. Can be kept in freezer for days, if it lasts that long!
