You've really made me think Eccles.
I used to use it a lot more than I do now, these days it rarely gets used.
I use it for grilling bacon, sausages (I don't like frying sausages as they roll about in the pan, they sit nicely and cook more evenly under the grill) and cheese on toast. And for doing the sugary top of a fresh fruit brûlée..I have a kitchen flame thrower but feel I get a better outcome from shoving it under a very hot grill... not that I make brûlée very often.
I used to always grill steak, when there were four of us at home it was more convenient to put all four steaks under the grill than do two at a time in the frying pan. Now there's just me and him, I fry them.
Mine is a waist height grill which can also be used as an oven, it only gets used as an oven on Christmas Day when I'm pushed for oven space. And then it smokes the kitchen out...
