The Bruges’ swan, or het brugsch swaentje in Belgian, is a variety of Belgian chocolate praline that has been produced since 2006. Although the exact method of preparation and ingredients remain a well-kept secret, this sweet specialty is typically prepared with dark, milk, or white Belgian chocolate surrounding a filling of almond paste, traditional lace biscuits (kletsekoppen or dentelle de bruges), and a unique mix of spices called gruut, which has traditionally been used for brewing beer.
