1Wash the potatoes. Cut each potato into 3-inch lengths then cut into 3/4-inch-thick wedges.
2Put the potatoes in a large saucepan and cover with cold water. Bring to a boil and cook for 4-5 minutes until almost tender, the potato should still be firm when tested with a skewer. Drain in a colander.
3Line a large tray with a clean tea towel. Spread the potatoes in a single layer on the tray. Set aside to cool for 15 minutes.
4Preheat the oven. Select AIRFRY/SUPER CONVECTION/400°F/30 minutes and press start.
5Put the salt, pepper, paprika, cumin, cayenne pepper, coriander and Cajun spice mix in a large bowl. Transfer 1½ teaspoons to a small bowl and set aside. Add the oil and mix well. Add the wedges and stir gently to coat.
6Place the wedges into the AIR FRY basket, ensuring they are not touching each other.
7Once the oven has preheated, place the basket in the AIR FRY position and cook for 30 minutes until crisp.
8To make the lime aioli, combine all the ingredients in a bowl. Cover and refrigerate until you're ready to serve.
9Place the potato wedges on a serving plate. Sprinkle with reserved spice mix and serve with lime aioli.
