Place maple syrup, butter and salt in a small sauce pan.
Place candy thermometer into syrup mixture. Cook on medium high heat until temperature reaches 235 degrees (the soft ball stage). This takes approximately 20 minutes (give or take).
Once the syrup mixture reaches 235 degrees, remove from heat.
Now comes the fun part! The first thing you need is a large cookie sheet to slide under a clean layer of snow. You do not want to pour it directly onto the snow or it sinks down to the ground. From this point you can drizzle your syrup mixture directly onto the snow or you can bring the tray inside and drizzle it on the snow inside your home. We have done it both ways. I personally like it best outdoors!
Once all the syrup is drizzled, you can pick up the beautiful caramel ribbons and enjoy. The caramel is best served immediately.
