Kardemommeboller are traditional Swedish cardamom buns. This sweet knotted pastry is usually made with a combination of milk, butter, yeast, sugar, flour, crushed cardamom seeds, and salt. The milk is scalded and mixed with butter until everything is melted.
The combination is mixed with the sugar, salt, cardamom, yeast, and flour in order to make a stiff dough. The dough is left to rise and it's then rolled and folded over into knots. They're baked for a few minutes, then brushed with butter while still hot.
