If goes without saying that baking a lone potato or roasting a handful of nuts in the oven not only wastes energy, it also doesn’t make economical sense. Compared with the hob, an oven can be expensive to run so if you’re using the oven it’s sensible to try to make the most of the heat and space by cooking a number of things at the same time. Batch cooking or doubling-up recipes to be frozen or chilled for the week ahead are a great way of planning, saving time and money.
