Ingredients
Home-kitchen amounts for 2 — standard home-cooking quantities for this dish, not the chain’s recipe (chains do not publish theirs). Difficulty: Medium.
- 300 g wagyu beef mince (or the best-quality beef mince you can buy)
- 2 traditional or panini burger buns
- 2 slices aged cheddar
- 8 dill pickle slices
- ¼ Spanish onion, thinly sliced
- Egg mayonnaise: ½ cup mayonnaise, 1 hard-boiled egg yolk, mashed, 1 tsp Dijon mustard
- 1 tbsp Dijon mustard, extra
- 2 tbsp tomato sauce
- Salt and cracked pepper
Method
- Stir the egg yolk and Dijon into the mayonnaise to make the egg mayo. Form the mince into 2 thick patties, season well, and rest 15 minutes. Handle wagyu gently — it is soft and rich.
- Cook on a barbecue or in a hot pan 3–4 minutes per side. Add the cheddar for the final minute.
- Toast the buns until just golden.
- Spread egg mayonnaise on the crown and Dijon and tomato sauce on the base. Layer pickles and onion, then the cheesy patty.
- Rest 2 minutes and serve. Tip: wagyu is rich, so keep the build simple — the pickles and mustard cut through the fat, and piling on extra sauces drowns the beef — and do not press the patties, or the fat (and the flavour) runs out.
