I’d bet a £2 steel Yorkshire pudding tray is more durable than a £50 porcelain one (it was porcelain, by the way).
Hold on a bit though. I’m not endorsing £50 Yorkshire pudding trays but I can see the advantage of ceramic. To make good Yorkshires you need to have the tray piping hot so that the batter starts to bubble and cook as you put it in. Having a ceramic one would mean much greater heat capacity and more crispy light Yorkshires, I reckon. But your point still stands about the cost.
Other things that are expensive and mundane:
Fence post, £15 for a piece of wood to make the fence exactly as it was before. Likewise car exhausts – £250 and no upgrade, no better anything. Just the same as it was. That’s the nature of repairs I suppose, but’s a little irritating not to be able to upgrade to anything at the same time.
