2In a 3 quart saucepan, mix together sugar, milk, corn syrup, pumpkin and salt. Bring to a boil over high heat, stirring constantly. Reduce heat to medium and continue boiling. Do not stir.
3When mixture registers 232 degrees F (110 degrees C) on candy thermometer, or forms a soft ball when dropped into cold water, remove pan from heat. Stir in pumpkin pie spice, vanilla, butter and nuts. Cool to lukewarm (110 degrees F or 43 degrees C on candy thermometer).
