Accidental savings when cooking

Retained Heat Cookery

This may be the new wave of thinking about how we cook in our budgets.
What with energy costs being what they are and only sure to go up
I now factor in the energy cost to cook things.

I did not know this about the boiling of eggs I will have to try that.

Lately to have a super cheap meal I just open a can of room temperature
beans with my hand operated can opener and have a no energy cost
meal.

Never heard of such a thing, good tip though I'll have to try it.

Does it work like that for everything or just for Eggs & Noodles?
