To make the Mac patty:
- Start by making the béchamel sauce. In a saucepan, melt the butter over medium to high heat until it starts foaming.
- Add the baker’s flour and stir-cook for 1 to 2 minutes.
- Remove the saucepan from the heat and gradually whisk in the milk until the mixture becomes smooth.
- Return the saucepan to the heat and cook for 10-12 minutes, stirring with a wooden spoon, until the sauce comes to a boil. The sauce should thicken and coat the back of a wooden spoon.
- Take the saucepan off the heat and stir in the 1.5tbs salt and pepper.
- Allow the béchamel sauce to cool, then transfer it to containers and place a sheet of baking paper over the surface to prevent a skin from forming.
- In a large mixing bowl, combine cooked pasta, 1kg béchamel sauce, Parmesan cheese, cooking cream and Dijon mustard and mix thoroughly. Season the mixture with salt.
- Line a baking tray with baking paper and evenly spread the mixture into it.
- Bake at 180˚C for 12 minutes, then allow it to set (press) in the refrigerator.
- Once the macaroni slab is set, use a ring cutter to cut it into patty-sized portions.
- Set up a crumbing station and coat the mac patties with egg, milk, flour and breadcrumbs.
- Pre-heat deep fryer to 180˚C and cook the mac patties until golden brown.
To make the bacon jam:
- Finely dice the bacon and add it to a large frying pan. (Don't worry if the bacon pieces stick together; they will separate as they cook.)
- Cook the bacon over medium-high heat for about 10 minutes, stirring frequently, until it is cooked but still quite chewy (a few crispy bits are okay).
- Using a slotted spoon to drain the oil, remove the bacon from the pan and set it aside. Keep one tablespoon of the bacon drippings and reserve the rest for another use.
- Add the onions to the pan and cook for about 8-10 minutes.
- Reduce the heat to low and stir in the sugar.
- Continue cooking until the onions have caramelized, about 10 minutes.
- Increase the heat to medium and add the espresso coffee, ½ cup of water, and the bacon to the pan.
- Cook the mixture, stirring every five minutes, until the onions are thick and jam-like, approximately 30 minutes.
- Remove the pan from the heat and stir in the balsamic vinegar.
- Season with salt to taste.
To make the wagyu beef patties:
- In a mixing bowl, combine beef mince, beef fat and salt. Mix until well combined.
- Shape the mixture into burger patties, aiming for approximately 160 grams each.
- Grill patties until cooked
To assemble the burger:
- Start with a lightly toasted buttered bun as the base of the burger.
- Spread bacon jam evenly over the base of the bun.
- Place the mac patty on top of the bacon jam. Melt Hi-melt cheese on the mac patty.
- Add the Wagyu patty on top of the mac patty. Melt Swiss cheese on the Wagyu patty.
- Layer McClure pickles and sliced tomato onto the burger.
- Finish by adding whole leaf lettuce.
- Finally, top it off with the other half of the bun, slathered with batch No.5 aioli.
