500 grams good quality beef mince (not low fat)*
250 grams lamb mince
100 grams (4 slices) sharp white cheddar, sliced
2 teaspoons sea salt**
2 teaspoons freshly ground black pepper
4 sandwich-size English muffins
Parsley-Shallot Butter (recipe below).
Run your hands under very cold water for a minute, then gently combine the two meats.
Put parchment or film on the electronic scale before weighing, please. Divide the meat into equal portions (170 grams each) and then gently form portions into patties that are 1¼" thick and 3" in diameter.
Season each burger all over—top, bottom, and the circumference—with ½ teaspoon salt and ½ teaspoon black pepper. Hold your hands high and “rain” the salt and pepper.
Touch the patties as tenderly and as little as possible. The more you manhandle and compact the meat, the tougher it becomes.
On the medium-high heat section of the grill, place the burgers 2 inches apart from each other. Cook to accurate temperature. For medium rare, cook for 7 minutes on one side, flip, and cook for 5 more minutes. Do not turn, touch, press down on, or otherwise molest the burgers while they are cooking. Put burger on a sizzle plate, place cheese on top, and drop under the broiler until the cheese is just melted but not liquefied.
Split the English muffins by deeply pricking them along the horizontal seam with the tines of a dinner fork.
Toast well and generously schmear both the tops and the bottoms with the room temperature parsley-shallot butter, “wall to wall” as we always say at Prune, so that every bite will be seasoned and not just the center ones.
Place the burgers on the bottoms and close with the buttered English muffin lids.
