A gourmand and irresistible version of a fast food classic. This dish suggested by the Cullera de Boix restaurant chef, Xavier Matarrodona, consists of a beef hamburger with onion confit, foie gras and truffle sauce. Savour it slowly (almost with the same patience it takes to make the onion confit) and enjoy all the flavours and aromas of a recipe that goes beyond traditional hamburgers. Try to prepare an almost luxurious burger!
