Being a good OzBargainer, I thought I am pretty thrifty when come to minimising spending in my household, or maximising my dollar, another way of looking at it. How about you? Would love to hear from you.
One of them being using residual heat. When roasting in oven for example, I always turn off the oven for about 20 minutes before the desired time, and let the roast or whatever food sits in the oven for a while. Nobody in my family does this (I have hubby and relatives cooking in my kitchen from time to time). They remove the tray straight out of the oven after they turn it off.
The same applies to stove. I always turn it off between 5-10 minutes before the desired time, depending on what I am cooking. My favourite is boiling eggs. For upto four eggs, I set the stove to turn off at 7 minutes, and let it sit there for another 5. I thought my eggs are perfect that way.
That's exactly what I do. I also open the oven door after cooking and use it as a heater to warm up the kitchen. Turning your heater off 10-15 minutes before you leave the house ( or don't turn it on at all to save money!). Put your hands under your laptop to warm up!
