Substitutes

Has anyone found a sugar-free recipe for a clear corn syrup? I found an easy sugar-free for brown sugar: 1 cup Splenda + 1/4 cup sugar free pancake syrup, It is supposed to deliver the sweetening of 1 cup of brown sugar. I liked it in my holiday
cookies.
Also, KW or B-man or Aline or readers, when a candy recipe [brittle or chocolate] calls for a buttered foil, can a silpat be used instead to eliminate fat ?
Many thanx to all this year for sharing such interesting recipes. Kathy
