Yes, snow. It's safe, provided you follow a couple of guidelines. A very important one is that you don't want to get snow as soon as it starts falling. Wait until it's been falling for about an hour at least, that way the general dirt/pollution in the air will be on the ground and not in your ice cream. Ideally, you want to have a snowfall of several inches before you start scooping snow. When you do scoop it up, leave about 1 to 2" on the ground - this is the layer that will have the dirt/pollution from the atmosphere. It needs to be clean snow, nobody has walked on it, no tree leaves or debris, and it goes without saying TO AVOID SNOW THAT IS YELLOW! It's best if you can get it from an area where there has been no animal activity, if we are going to make snow ice cream we get it from the front yard and not the back yard since the dogsters are back yard babies. Ideally, you should put a large bowl out where it can catch falling snow - preferable plastic and not metal! Measurements are approximate, which is normal around my house.
Snow Ice Cream
Fresh snow, at least 3 or 4 cups but as much as you can get. You can add more to the mixture as you mix it, if needed.
1 cup sugar (more if desired)1 or 2 eggs (can be skipped)
Milk, the amount is determined by how creamy you want the ice cream to be
Vanilla, at least 1 teaspoon
Mix all ingredients thoroughly, add the milk last. Add the milk in small amounts and stir, then add more if you think you need it. The snow will start out looking like a lot, but it will melt down as you mix it and you might need to add more to it.
It's best if you eat it as soon as it's made, it can be frozen but keep in mind that snow is basically ice and it will freeze very hard, like ice.
