Yes I am (or did) throw some microwaves into the mix [member=26580]Backinwellies[/member] - I won't do it again. Haven't re-tested w/o alu' tray for a while though as I'm avoiding pastry right now due to the covid waist-line expansion syndrome !
[member=212379]naturelovingfarmer[/member] - Thanks kindly for your thoughts. I'm not sure what you mean by an infra-red stove and equally I'm not sure what sort of heating element is in my multi-oven for convection or grill modes. However, in passing: I did try a halogen air-fryer-type cooker with glass bowl for a while until the bulb died - turned out that the bulb was not a 'plug-and-play' type: I didn't bother replacing it, despite some good cooking results, because I was getting fed up with awkward hand-washing of a 17 ltr bowl that could not be put in the dish-washer apparently. Also, I did once cook a whole Xmas turkey dinner, for my 2 kids and me, using just my original micro-wave multi-cooker !! In retrospect, if I'd had any sense I could have used a camping stove for boiling the veg, but it didn't occur to me at the time. Never-the-less, the dinner was, I have to say, a juggled success - even the gravy !! So, junking a conventional oven/cooker is not something that fazes me: it's just a matter of getting used to routinely doing all things differently (compared to conventional cooker) as my new standard. I'm not interested in going back to a standard cooker/oven and my old micro-multi lasted almost 20 years (albeit along-side a traditional gas/electric range cooker) - fingers-crossed/touch wood for the longevity of its replacement supported by the Instant Pot.
