Ingredients
For the minty mayo:
- 100 g mayonnaise
- 2 heaped tablespoon fresh mint leaves, finely chopped
- extra-virgin olive oil
- 2 tsps cumin seeds
- 2 large red onions, thinly sliced
- ½ tbsp balsamic vinegar
- ½ tbsp sugar
- 500 g lamb mince (10% fat)
- 2 heaped tablespoon rose harissa paste
- ½ onion, grated or very finely chopped
- 2 garlic cloves, minced
- ½ tsp fine sea salt
- ¼ tsp black pepper
- 4 brioche burger buns, halved horizontally
- 1 large handful rocket
Instructions
- Start by making the minty mayo: add the mayonnaise and mint to a small bowl. Season with a small pinch of sea salt and lots of freshly-ground black pepper and stir to combine. Set aside.
- On to the cumin caramelised onions. Heat a splash of extra-virgin olive oil in a saucepan over medium heat. Add the cumin seeds and cook, stirring constantly, for 1 minute.
- Add the onions and season generously with sea salt and freshly-ground black pepper. Reduce the heat to low/medium-low and cook, stirring occasionally, until very soft and caramelised, around 30 minutes. Don’t rush the process! Caramelising onions takes time. If the onions start to catch, add a splash of water to the pan and stir to combine.
- Add the balsamic vinegar and sugar and stir to combine. Cook, stirring frequently, for a further 2 to 4 minutes, or until the onions are nice and sticky, the sugar has dissolved and the balsamic vinegar has reduced. Set aside.
- On to the patties. Using your hands, combine the lamb mince, rose harissa paste, onion, garlic, salt and pepper in a bowl and mix until well-incorporated and evenly combined. Divide the mixture into four and form into patties.
- Heat a large frying pan or griddle over medium heat. Cook the lamb patties for 4 to 5 minutes on each side, or until cooked through. You can finish them in the oven for a few minutes if necessary. Transfer to a plate and let rest for 5 to 10 minutes.
- While the burgers are resting, toast the buns in the same pan used to cook the patties. To assemble, spread a heaped tablespoon of the minty mayo on the base of each bun. Top with the lamb patty, a heaped tablespoon of cumin caramelised onions, a small handful of rocket and the top bun. Serve and enjoy!
