Authentic Scottish food isn't 'fancy', but it's wholesome, filling, generally easy to prepare and surprisingly tasty when you realize that spices aren't commonly used... salt and pepper being the staples.
Centuries ago, stews, broths, soups, haggis, fish and porridge were what most Scottish people ate regularly.... basic meals that kept the ancient Scots warm and gave them the strength and energy they needed.
The 'heavy', starchy nature of many meals helped to keep stomachs full for a long time too. When encouraging me to eat porridge for breakfast, my Nana used to say "that'll stick to your ribs"... and you know what, she was right!
