*Dip apples in boiling hot water for a few seconds to melt and remove wax.
**Make sure your candy thermometer is calibrated correctly. Boil some water and allow the thermometer to sit in the water for a few minutes. Make sure it's not touching the bottom. The thermometer should read 212 when the water is at a rapid boil. If not, adjust thermometer or take difference into account when cooking the caramel.
