My first experiment was a couple of butchers pork sausages for lunch. If I cook them on the hob they splash oil all over so I end up having an extra cleaning job, under the grill they tend to do the same and tend to produce quite a bit of smoke and the odd flame!
You can use foil in the bins so I lined one of the bins and shoved the sausages in, set the recommended temperature and time and set the turn timer to tell me when to flip the sausages. End result, pleased to say, perfectly cooked and browned sausages using no oil, winner.

One of our friends has recommended using silicone bin liners to save on the washing up of the bins and integral removable trivets which are not dishwasher safe so have to be washed by hand and handled with care. The silicone liners are reusable of course and dishwasher, fridge, oven and microwave safe so it makes sense.
I went online and it would seem that the Ninja brand of fryers have cornered the market, just about every result is for the Ninja 3000 machine. This particular model has smaller bins than ours so the hunt was on to find some a bit bigger. Took a while but I eventually found a pair specifically for a Ninja model which is a bit nearer to the dimensions of the bins on our machine so I have ordered them, they should be delivered some time next week. Ordered from Amazon so I popped an Air Fryer recipe book on the order as well, New to this style of cooking so a bit more information will be welcome.

I thought this new topic may be useful for anyone else who already has or is contemplating a similar purchase.
