My folks were over for Christmas and we had some potatoes O'Brien for breakfast - just a frozen mix you do up in a frying pan.
It was taking AGES. I could have sped it up moving over to the mega burner, but that would have made the searing heat coming around the sides of the pan even worse! It was damn-near painful to stir that stuff around with a wooden spoon, and it took like 20 minutes to fry up nicely.
They're not fast, folks! They just react quickly. That's it.
