Swedish Punch - or Punsch - is a liquor which contains rum, sugar, and spices, and harks back to the Swedish East India Trading Company. The sailors were kept mollified with Batavia Arrack which they apparently doctored with the above ingredients to make it drinkable. At some time in the 19th century, the concoction was bottled and sold as "Swedish Punsch".
