Brrrr. It looks like it’s going to be an early winter this year. Here’s a delicious drink , a classic, that is meant to be sipped while bundled up in an old plaid blanket or sitting in front of a fire. Whip up a batch to keep in your refrigerator for those chilled-to-the bone evenings or pack it into pretty little jars to give, along with a bottle of rum, as a holiday gift. This couldn’t be simpler.
