While the Oven's On - One Flame Again

Being a mean beast who cuts things very fine (Ratty in Wind in the Willows) I don't like to use the oven for just one thing, especially as ours is one of those with a double-sized space one side and a mini version (only ever used to warm plates) the other. So I try to remember to include a few unpeeled onions to give the makings of a simple onion with cheese veg dish, some beetroot, or baking potatoes, or most often a gratin.

The one-flame cookery idea easily incorporates such economy, as why should one flame mean on dish only? Saturday's party (very enjoyable thanks) included a 6lb brisket dry rubbed with spices and sugar roasted at about 120C for nearly eight hours. That would have been a profligate use of the oven had it been just for one dish. So I also did a big potato gratin, loads of onions, loads of cheddar, slow cooked for two and a half hours, and a toffee-crumb apple and quince pudding, conscious assuaged.

Gratins are such a simple thing to do as I was explaining to hopefully-soon-to-be student Sternest Critic. What they do need is time and thus patience. It's not something to throw together for a quick snack. And they can be very cheap filler-uppers. That was secondary in my thinking for the bonfire bash for which its forgiving nature was uppermost in my thoughts: it was ready a good half an hour before I took it out, but didn't spoil at all (if anything the cheese got a nicer browning) for being left longer, and could have remained at that heat without damage for another hour. Again it could have been cooked at 180C and been ready in less than half the time.

It's also the sort of cooking I love - no recipe, just a basic idea and method. If you have to weigh the ingredients for a gratin you're trying too hard. Just peeled and sliced spuds and onions (the latter very thin), grated cheese, layered onion-spud-cheese  then repeated, a bit of salt and pepper, and cooking liquid (hot) which can be milk, milk and cream, stock or at a real pinch just water. The alchemy of baking turns these basic staples into a meltingly delicious whole. We have lots of celeriac on our allotment, another grateful for the gratin treatment, and parsnip likewise, so I have no excuse for not doing more and bringing in more variations as autumn turns to winter.
