Putting the oven on is expensive, so when it’s on, make the most of it.
Mine was on for some breakfast sausages (I know – naughty, but I’ve been good all week, and they’re going in a ciabatta with lots of ketchup and mustard). Later I’m making a roasted cauliflower pasta, so the cauliflower is going in now to roast. I’m also baking a couple of potatoes to keep in the fridge for when I’m peckish.
One oven, three jobs. It saves energy and it saves money. Top tip.
