Let the powdered gelatin soak in the chicken broth for like 5 to 10 minutes in a bowl that can go in the microwave. Heat it in the microwave in short bursts 'til everything’s melted. Once it’s good, let it chill in the fridge for a few hours. When firm, break it into bits if you’re adding it in.

Get your pan cozy over medium and melt up some butter. Toss in those finely diced onions and let them get soft and a bit caramelized. Next, pile in the ground beef and cook it till you see some browning and it smells awesome.

Splash in Worcestershire and mirin, let it bubble until it’s pretty dry. Take it off the heat and let the mixture hang out till it’s room temp.

In a bowl, mix milk with the panko breadcrumbs so they soak it all up. Just let it sit a bit.

Toss the ground beef (the bigger amount) in a bowl. Add pepper and salt, that panko-milk mixture, egg yolk, ketchup, sugar, a touch of nutmeg, and all that cooled beef-onion yumminess. If you want, add the jelly bits now. Mix it until everything’s pretty even.

Divide the meat so you get 4 rounds, then shape each into flat ovals. Lay ‘em out on a tray, cover them up, and let them chill hard for half an hour in the fridge.

Sort your plates: one gets the flour, another the beaten egg, and a last one for the panko breadcrumbs.

Take each cold patty and roll it in flour, tap off the extra, dip in that egg, then roll in breadcrumbs. Want them extra crunchy? Repeat the egg and breadcrumb dip and gently press them on so they really stick.

Heat your oil in a deep pan to about 160°C. Drop patties in (a few at a time so the oil stays hot) and fry them on both sides for 2 minutes each.

Lift the patties out and rest them on a rack. Bring the oil up to 180°C, toss the patties back in, and fry both sides again, 1 or 2 minutes, so they’re mega crisp and golden. Move them to a rack to drip off the oil.

Just grab a bowl, throw in ketchup, Worcestershire, oyster sauce, a little olive oil, and a splash of rice vinegar. Stir till smooth.

Serve the patties up, pour that sauce over, toss on the parsley, and enjoy them hot.
