1-First Step: Mise en Place and Mixing Start by gathering and prepping your ingredients, like finely dicing the yellow onion and mixing any optional chicken stock jelly. In a bowl, combine the raw ground beef or beef/pork mix with salt, pepper, the breadcrumb mixture made from panko and whole milk, egg yolk, tomato ketchup, sugar, and nutmeg powder. Add the cooled sautéed onion and meat mixture for even flavor distribution.

2-Second Step: Shaping the Patties Divide the meat mixture into equal portions and shape them into oval or disc patties. For the best results, rest them in the fridge for 30 minutes to firm up, which helps with texture. If adapting for dietary needs, use plant-based mince here for vegan options, adjusting binders as needed to keep the patties intact.

3-Third Step: Dredging Sequence Set up three plates: one with all-purpose flour, one with whisked egg, and one with panko breadcrumbs. Coat each patty first in flour, then in the egg wash, and finally in panko; repeat the egg and panko for a double layer. For gluten-free versions, use gluten-free flour and breadcrumbs to ensure the coating sticks without issues.

4-Fourth Step: Frying Technique Heat your cooking oil to 160°C (320°F) and fry the patties for 2 minutes per side, making sure not to crowd the pan. This gentle fry cooks them through. Drain on a wire rack, then crank the oil up to 180°C (356°F) and fry again for 1-2 minutes per side until golden and crispy. For a lower-fat method, bake at 200°C (400°F) for 15-20 minutes, checking for an internal temperature of 71°C (160°F) to ensure doneness. Texture checks: The outside should be crunchy, and the inside juicy.

5-Final Step: Resting, Slicing, and Serving Let the patties rest on a rack to drain excess oil, then slice if desired and serve with the homemade sauce mixed from tomato ketchup, Worcestershire sauce, oyster sauce, olive oil, and rice vinegar. Garnish with dried parsley for a nice finish. For vegan adjustments, use oil-based coatings instead of egg, and pair with sides like rice or veggies to complete the meal.
