So having decided that the current dual basket (5/3L) air fryer we have is definitely flaky (see "air fryer beeping" thread) replacing it seems a good idea. Especially as it's covered by a 3 year guarantee.
However the same model is no longer available from the retailer - it seems that dual baskets are almost exclusively symmetrical 4/4L. (I suspect this is manufacturers driving consumer choice).
The annoying thing here is the 5L basket (19cm width) we have takes 3
10cm frozen burgers completely flat. Any smaller (e.g; 15cm width for a
4L version) and it's not possible to lie all 3 flat.
I will be experimenting with standing them vertically - however I wondered if anyone here has any advice.
As usual Googling now just returns recipes or retailers for air fryers and burger. And I really can't face any more redditing this year.
