Sisemen don't give up on the air fryer, as with anything new it's worth experimenting with different recipes which abound on the www. For the chips we followed the recipe in the Philips booklet and they are excellent. For the fish cakes the other day I used my usual recipe and then found a suitable guide to cooking them in the air fryer using good old giggle. The fish cakes turned out much better than conventional frying.
It was the same with the bread maker, a few dodgy loaves but now I can produce very nice bread and cakes thanks to a bit of trial and error.
As regards the air fryer it has turned out to be well worth the huge expense of importing it into Bots.
