Sure, but you want to go as hot as possible to get the oats cooked. Besides, I wanted to be as quick as possible. Like, quick oats, you know? ;-)
Nah, sorry, I don’t know.
Rolled oats don’t need to be cooked.
If you want soft outs you can soak them over night in the fridge.
No heat required.
The power setting just pauses the power for % time like your doing manually. I do 70% for my oats in a big bowl so the bubbles die down before the power repeats.
