Faux Schlow Burger, originally uploaded by Coyoty.
Burger with cheddar, onion rings, and horseradish sauce. From Tunxis Community College's Corner Cafe in Farmington, CT. (Horseradish sauce from Arby's.)
The Schlow Burger was created by Michael Schlow for the Food Network's South Beach Food and Wine Festival in Florida in 2008. His version used crispy fried onions and a horseradish sauce made from mayo and prepared white horseradish. Mine was very good, but I think his would be better. It's worth trying again with better ingredients.
