General tips
Kitchen Tip : Match the size of the pan to the heating element; more heat will get to the pan and less will be lost to the surrounding air or found by the pan handle! A 6-inch pan on an 8-inch burner will waste over 40 percent of the energy.
Making your own lunch instead of buying from a sandwich shop saves on packaging, and could also save you approx £4 a day or £1,000 per year!
