Preheating: A Waste of Time
No nutritional value gained, journal says
(HealthDayNews) -- Next time you see a recipe that calls for a preheated oven, forget it.
Foods cooked in a non-preheated oven taste as good, look as good and are as nutritious as those cooked when the oven was brought up to cooking temperature first, reports the Journal of the American Dietary Association.
And since the extra cooking time is less than the time spent preheating, you'll save energy.
