Pacho’s Burger Truck is named after Asel Dehsabzi, nicknamed Pacho, who runs the patty-smashing joint with his sister Tabby Dehsabzi. The burger joint is parked near a Rozelle petrol station, the sound of sizzling patties competing with the hum of Victoria Road traffic.

Onions are smashed into most burger patties the siblings serve, “so you get that nice onion pull when you bite into it,” says Asel. In fact, it’s a key attraction of their Oklahoma; the rich, caramelised onion flavour is so compelling, they choose not to add sauce, lettuce or tomato.

Pacho’s Burger Truck aims to do a monthly special. In the past, there’s been a kofta smash, inspired by a visit to their Lebanese butcher whose shop was overwhelmingly fragrant with fresh herbs, which he was chopping for his beef and lamb kofta mince. It hit a bun with a lemony tahini spread and diced pickled turnips.
