It's time to board a small charter flight to Polynesia, the land of Spam and pineapples. Why Spam and pineapple? Because it's a delicious combo that hits the rich/fresh/sweet flavors and the crisp/moist textures. Who wouldn't want that on a burger? Add a couple of slices of Swiss cheese along with a nice spoonful of sriracha-mayonnaise and the burger explodes with spice and goo—which is why a toasted English muffin and all its juice-catching nooks is such a great choice here (though regular burger buns would be mighty tasty too).
