I've been burger crazy, lately.
It started last summer, when I made the grilled pork burgers recipe from the Lucques cookbook--ground pork, chorizo, and bacon burgers, topped with romesco and manchego cheese: yes, they're incredible--but it's kicked in properly over the last couple of weeks, as I've been making burgers from Great Burgers.
Thus far, our favorite has been the Negimaki burgers, with the Picadillo burgers (which I made tonight) a close second. But the best part is perfecting the mixing, the timing, and the process of making the burger: I like to get better and better at things as I make them more often, and the benefit of burgers is that I can make many variations on the burger whilst still improving the basic techniques.
