Stir constantly throughout to keep the sauce smooth and prevent scorching. Don't skip the corn syrup, since it keeps the sauce from crystallizing. Add the vanilla off the heat for the best flavor. The sauce thickens as it cools, so a thin hot sauce will reach the right pourable consistency once cooled. For salted butterscotch, add a splash of bourbon or extra salt at the end. Store in an airtight jar in the fridge up to 2 weeks; it firms up when chilled, so warm gently before serving. Makes about 1 1/2 cups.
