The packet says microwave 90g for 1 minute 20, if I want to do the hole packet (450g), do I just microwave it for six minutes (or doesn't it work like that)? Thanks
No, we work on the principle that you add half again for volume, not 5 times. If you are microwaving one dish for 6 mins, and want to do two, I'd do the lot for 9 mins. Seems to work for us.
anlyn: obvious, but incorrect. The relationship between amount and time isn't linear. If you double the amount of food, cooking time increases by 50 to 75% - depending on lots of other variables.
Just do it a bit shorter time then, sher, if yours is more powerful. Better to do it in short bursts then test and put in again if necessary, that overcook in the first place.
Or - peasy - divide into 5 portions and do each separately :-)
