Preparation

To build danish sandwiches, a slice or two of whatever chosen topping (i1/2palgi1/2) is placed on a slice of buttered bread. Toppings are artfully added to create a tasty sandwich -- with visual appeal!
When at home with friends, people pass dishes of sliced breads around the table, and then to pass around each dish of toppings, and make their own sandwiches.
In Denmark, Danish sandwiches are typically eaten with a fork and knife.
