Cooking for only one or two of you? Have you thought about investing in a halogen oven? Generally there’s just me and OH at home and I don’t always want ( or have room in freezer ) to batch bake to utilise the whole oven when it’s on.
So at the end of the year I brought a Halogen. I was skeptical before buying but I knew I could send it back if I didn’t get on with it. OMG I love it ! Had no failures with cooking in it and it’s far quicker and cheaper to use than the main oven. You don’t have to wait for it to heat up and cooking time is cut. You can pick a new one up in Aldi for as little as £25, yes some models are way more but it’s a piece of equipment I don’t regret buying
I bought a second hand one after reading your posts on fyf20. I love it. I always felt too guilty to use the oven for one thing but now use the halogen. The oven doesn’t dirty as quickly now either. Love it.
