  1. Make the same as a hot rum sling.
  2. Add a teaspoonful of butter and serve hot.

This is a concise but important restorative branch of the hot-rum service line.

The butter changes both body and service identity while leaving the sling base intact.

This keeps the rich hot-rum restorative line visible in a genteel sideboard context.

The butter is integral to the drink identity, not a decorative flourish.
