Make the special burger sauce – To make the sauce, add all the ingredients to a small bowl, mix well to combine and set aside.

Spread the beef on the tortillas – To make the tacos, divide the minced (ground) beef into 8 equal portions. Working with one portion at a time, spread the beef over 1 tortilla, leaving just a 5 mm (¼ inch) border around the edge. The beef will shrink as it cooks, so try and get the beef as close to the edge as possible. Repeat with the remaining beef and tortillas.

Cook the tortillas – Heat a large, heavy-based frying pan over medium–high heat.

Sprinkle each beef-topped tortilla with salt and pepper right before cooking (do not add the salt and pepper until you are ready to cook, as it can make the beef tough).

Spray the frying pan lightly with olive oil, then carefully place a tortilla in the frying pan, meat-side down. Cook for 2–3 minutes, then flip and cook for a further 15–20 seconds. If there is still residual liquid around the beef, flip it again and cook it for a further 30–60 seconds. Once the beef is cooked to your liking, flip the tortilla beef-side up and place a slice of cheese on top. Remove the tortilla from the heat – the heat from the beef will melt the cheese. Repeat with the remaining tortillas. I normally cook two tortillas at a time. Keep them warm in a 120°C (250°F) (100°C/200°F fan-forced) oven if needed, or top them and serve immediately.

Assemble the tacos and serve – Top each taco with lettuce, pickles, onion and the special burger sauce.
