An incredible treat by many names with one ingredient. Maple syrup. Known as maple taffy, maple toffee, tire d'érable, or sugar on snow, it is delicious and easy no matter where in the maple-producing north american region you are!
No snow? Tell me about it, I live in San Francisco. Our last snow was in 1976. If you don't live in a winter wonderland, You can use Ice Cream(!), ice, or a frozen skillet. The snow adds texture, romance, intrigue, and all the particulate matter that lives in the atmosphere above you. A bit of googleing tells me this includes dust from the sahara and radioactive bits from your local power plant. Anyway, it tastes great!
Any grade, any sort. Grade B will have a stronger flavor, but whatever you have will work. I doubt it would work with fake syrups, but it might be worth a try.
