Probably not even 10-15 mins, I do it by "done-ness" i.e once they're browned as above and quite crispy as they brown quicker than they go crispy.
I thought about getting a chipper but quite like doing it rustically with a knife. our method is below..
For chips, key thing is getting the starch out and also to rough them up a bit to allow the roughed up parts to crisp up extra.
1) Cut the chips up
2) Put into a pan of water and add salt and vinegar and boil for 3-4 mins
3) Drain water, add cold water and more salt and vinegar. Drain cold water away - this cold water will stop the chips cooking and drain away the starch that came out of the chips.
4) Now you need to dry them so pat them dry and I chuck them in the air fryer for about 2 mins to definitely dry them off. As you take them out, rough them up a bit by shaking them in the basket - this gives little imperfections on each chip to help take hold of spices and herbs when you season them and crisp up better as the jagged bits get crispy
5) Now take a large bowl and add some oil, and whatever seasoning you want - I use whatever is handy but for example salt, pepper, garlic powder, chilli powder, white pepper, onion salt and a few others but go with as little or as much as you like and mix them around to make sure all coated with oil and seasoning - those little roughed up parts really helps here.
6) Put them back into the heated air fryer at 200 and cook for about 20 minutes (depending on thickness) but open the basket every 5 minutes and shake them about, this ensures all get evenly cooked. After ten mins I give them a quick spray with oil if I want them extra nice. A good oil sprayer is air fryer secret weapon for improving literally anything. doesnt have to be a ton.
7) Take them out when they're as done as you want them
Result!
Now when we do this, we do double the amount we want to eat, the rest go in the fridge, then next day air fry them again! Now they're triple cooked and they're even better! This also works with leftover fries from a takeaway or restaurant meal.
Using this method you can have them as thick or thin as you want, soft or crispy as you want, light or brown as you want etc and have them pretty much perfect every time.
It sounds like a chew with a lot of steps but honestly once you've done it once it's ridiculously easy
Also if people havent made use of the "reheat" function on pizza/parmo leftovers, need to get on the case. For pizza i microwave for 2 mins then a few mins in reheat mode - that cooks everything through then recrisps.
Yeah, I've been through the 10 steps methods before, and tried a billion different ways. The way I do it now isn't as good as my other methods, but it's 95% there, less faff and less washing up and I'm tight on time at the min. I think we've had this conversation before, but my method changed in favour of efficiency, rather than perfection. Your method will be spot on though, you know what you're doing!
You're 100% right that it's the starch and them being wet which wrecks all the plans. Vinegar is good for softening them up, and salt helps everything, other than slugs.
My quick/time-efficient way for the week:
I just chip up and rinse a load of them, let them soak in water for days (don't leave exposed to air or they go brown)
When I need a portion take some out, give them another rinse in silicone bowl with holes in
Microwave for 3 mins per portion in a silicone bowl with holes in (par cook/ par dry)
Chuck em in the air fryer for a couple of mins (till totally dry), take out
Back in the silicone bowl with a dash of high temp oil and whatever seasonings, mix up
Back in air fryer on max for 10-15 mins (shaking gently every 4 mins or so)
I've not tried the triple cooked way, can't imagine our lass would be up for that, although I'm well aware it's a good way, and if it's good enough for heston, it's good enough for me.
Pizza back in the air fryer is ludicrous, the microwaving step is good as it will put some moisture under the base too, and do some internal cooking before the outsides get blitzed in the AF. I do this sometimes, but most of the time tend to just dampen the base and crust and air fry at like 160, rather than 200+.
Give the iceland chips a go though, try the skin-on ones or salt and pepper ones, they're really good and much better than any of the others like Mcain etc. Come in handy for hangovers and CBA days.
