1. For the piri-piri oil,place all the ingredients except the oil into a blender and blitz until smooth,slowly adding the oil after 20 seconds. Place in a container and let sit for a minimum of 1 hour,but preferably overnight.

2. For the chicken,use a sharp knife or kitchen shears to remove the backbone. Then flatten it out by placing it skin side up on a cutting board and applying firm pressure to the breastbone. Rub with sea salt in both the cavity and skin before transferring it to a wire rack set over a foil-lined baking tray.

3. In a bowl,combine the 30ml piri-piri oil,smoked paprika,garlic,thyme and lemon juice and mix well to combine. Rub mixture all over the chicken and allow chicken to marinate for 1 hour or overnight.

4. Preheat oven to 240˚C (220˚C fan-forced). Roast the chicken,basting occasionally with extra piri-piri oil until cooked through,about 25 minutes. The juice should run clear when the thickest part of the thigh is pierced with a skewer.

5. Remove chicken from the oven,and allow to rest before carving and serving with extra piri-piri oil and lemon wedges.
