After several weeks of soul-searching, we've chucked out our cooker.
It was still working - just, but as there's only us two here these days, there really is no need to have a huge metal lump in the kitchen, taking up space, looking ugly, and needing much more cleaning than the Forth Bridge! Some flames from the grill had started to attack the dashboard a while back, and while manhandling it into the boot for the recycle guy in the village, I noticed what damage had really happened, so I'm glad it's gone!
So, we're investing in a whole new layout, with a small double freestanding hob, and just a counter-top oven, and life does seem so much easier already! Mrs O'Blene doesn't have to get down on the floor to rescue the heavy casserole, and we've discovered that the microwave does great grilled items for a fraction of the time!
I used to sneer at properties in tight urban areas, where they only had a microwave for company, but again, why heat up a cubic metre of metal just to have a slice of chicken!
