From About.com for ZWT #6's trip to Scandinavia. Delicious and satisfying fondue is made with bacon, Havarti and Gouda cheeses, and beer. Turkey bacon may be substituted for traditional pork bacon, if you wish.
Melt butter in a medium-sized heavy saucepan. Saute bacon and onion together until bacon is crisp and onion is golden. Add flour and cook for 2 minutes, stirring often. While continuing to stir, slowly add the beer and cook until sauce is smooth and thickened.
Add Havarti and Gouda cheeses to the sauce, stirring until melted. Transfer Danish fondue to a fondue pot and serve with dippers.
