I binned my deep fat fryer about two decades ago due to the grease it put in the air and the smell, horrible things. I'm not wild about fried food anyway but will make an exception for chips occasionally. I bought an airfryer a few months ago but have to say it's ok wouldn't rave about it. It's extremely easy to clean, you can hand wash it easily or put it on the top shelf of the dishwasher. Are they worth the money? I don't think so.

Even then lard was always available. Although fine for sauteéing and cooking potato for tortilla, etc., it is my experience that olive oil, like butter, burns at too low a temperature for crisp frying, so I use sunflower or rape seed for that.
