- 1 cup sugar
- 1/2 cup boiling-hot water
- 1/4 cup Scotch
- Cook sugar in a dry 2-quart heavy saucepan over moderately low heat, stirring slowly with a fork until sugar is melted and pale golden. Cook caramel, without stirring, until deep golden, then remove pan from heat.
- Carefully add boiling water and Scotch (mixture will bubble up and vigorously steam), then cook over low heat, stirring with a wooden spoon, until caramel is melted and sauce is smooth. Serve warm.
