Hunter-gatherers first came to Scotland after the ice age and ate meats, fruits and shellfish. The Vikings introduced smoking foods. In medieval times, common foods included oats, porridge, stews and fish. The potato later became a staple. Traditional Scottish foods include haggis, cullen skink, stovies, clootie dumpling, cranachan, irn-bru, scotch whiskey. Scottish people enjoy eating at home and debating whiskey, and have a fondness for sweets.
