Peel the potatoes and slice them into thin fries shapes. Think McDonalds type fries size.
3 Potatoes
Place the peeled and chipped fries into a bowl of cold salted water to soak for a few minutes (30 minutes or more works best but 10 minutes will be fine).
Drain the fries and then set them out on some kitchen roll or a tea towel to dry
Place back in the now empty bowl and tip in the oil and the Cajun mix. Mix thoroughly so the spice mix sticks on all the fries.
1 tbsp Cajun spice mix, 1 tbsp Vegetable oil
Cook in the air fryer on 200℃ for 20 minutes. Shake half way through cooking.
Notes
The salt water can be made by adding 1 teaspoon of salt to 1.5 litres of water. This should be enough to cover the potatoes.
