San Ignacio Green Chile Cheeseburger

["In a food processor, combine the mayonnaise, chipotles, and adobo until smooth. Refrigerate until ready to use. (This will make more than you'll need, so use the rest with artichokes or to dip tortilla chips, etc.)", "In a skillet over medium-high heat, heat the lard until it is shimmering. Add the green chiles and jalapenos and stir/toss for about 1 minute. Add the garlic and stir until fragrant, about 30 seconds. Remove the skillet from the heat and cool the mixture to room temperature.", "In a medium mixing bowl combine the cream cheese and the cooled chile-garlic mixture. Set aside.", "Divide the ground beef into 8 1/4-pound chunks. Press each chunk into a 4"" square patty, depressing the centers slightly more than the outer 1/4"" or so of the edges.", "Spread 1/4 of the cream cheese mixture on each of 4 of the patties, spreading it into a smooth layer in the indented portion of the patties. Place an unfilled patty upside down (indented side down) on each of the filled patties. Secure the edges by pinching all around the outer edges, then press the edges square again.", "Slightly toast the ciabatta rolls over the grill (or in the oven if you desire).", "Grill the burgers over moderately hot coals for 2 to 3 minutes on one side. Flip the burgers and cook 1 minute. Add 2 slices of cheese to each burger, close the cover and cook an additional 2 minutes.", "Slather a little of the chipotle-mayonnaise mixture on both the top and bottom of each roll. Place a burger on each one. If these burgers seem too much for the person eating it, they can be cut in half before serving, but let them cool a little first. Otherwise all that great filling will run out!"]
