From the N.Y. Times
There is undeniable pleasure in a plain beef burger — juicy, tender,
and well browned over a backyard grill — but there’s even more in a
jazzed-up one. If you begin with pork, lamb or beef that you buy
yourself and grind at home, and continue by adding seasonings
aggressively, you’re on your way to a summer full of great “burgers”
which are, in essence, sausages in burger form.
In fact, I wondered while making (and eating) my first pork burger of the grilling season: Why would anyone make a plain burger? Why would you begin with supermarket ground beef — whose quality is highly questionable and whose flavor is usually disappointing, if not depressing — and then cook it without much seasoning beyond a few crystals of salt? Ketchup, after all, does not fix everything. Even adding mustard, pickles and so on, right down to mayonnaise, doesn’t give you good-tasting meat.
