Tea was introduced into Scotland by Mary of Modena, the Queen of England, Scotland, and Ireland, between 1685-1689.
High tea in Scotland is very carb heavy, and involves hot food, as well as plenty of baked goods.
Afternoon tea can be pretty heavy, too, but doesn't usually involve hot food.
The best I can do for my nod to Scotland, is to enjoy some Scottish Breakfast tea. And maybe some carbs...
