Turkey mince smash burgers

Method

1. Begin by mixing all the sauce ingredients in a bowl with a pinch of salt and pepper. Set aside.
2. Split 2 burger buns, then use a serrated knife to cut the tops off the domed halves (see Tips). Flatten all 4 halves slightly with your hand, then toast in a hot dry pan on both sides. Split open the remaining 4 buns (as normal), then toast them on the cut sides.
3. Divide the turkey mince into 8 balls. Put a large frying pan over a high heat. Once smoking hot, add a dash of oil, then 2-3 balls of mince (depending on how big your pan is). Press down hard with a spatula to ‘smash’ them into thin patties. Sprinkle with salt and pepper and cook for a minute or so until caramelised and crisp. Flip over, add the cheese slices and cook for a minute more. Set aside and repeat with the rest of the balls.
4. Meanwhile, spread sauce over the cut side of each piece of bun. Sprinkle onion and lettuce onto the 4 bases and the tops of the flattened middles. Once the patties are cooked, put one on the base. Add the middles, then the second burger, 2 gherkin slices and the lid. Wrap in foil and rest briefly before serving.
