Oven. 1 1/2 hours at 200.
Nukerowave (4 spuds). 15 minutes at full nuke, then 45 minutes in oven at 200.
Air Fryer. Still experimenting but feels like for a couple of spuds 45 to 60 minutes at 180 on ‘bake’ setting works.
No oil, no salt, no nothing.
Mrs Noise would up all those times but she prefers the skins like dried out old leather…
