Use a large, wide & sturdy pan.
Fill with veg oil or sunflower oil (anything with a high smoking point) never more than 2/3 full as oil expands when heated & you don’t want it to spill over!
Heat the oil to around 180ºC (or test with a small cube of bread - it should fizzle & brown within 40 seconds).
Add the chicken carefully - do not overcrowd the pan & fry until golden.
Try it with my garlic aioli recipe.
