Gratifyingly Good Gratin

Nigel Slater is a cookery writer I find both helpful and annoying. His prissy style gets right up my nose, but he has some excellent ideas. Reading his recipe for baked onions with miso nudged me to make something with onions prepared in the same way - boiled for 40 minutes till soft (he said 25 - 30). My version then diverted from his entirely. Halved across the equator the onions were placed cut side up in a gratin dish, moistened with a dash or six of vermouth, then covered with a heavily peppered gruyere-and-brown-breadcrumb mix, dotted with butter, and baked in a 190C oven for 25 minutes or so (until the top crisped and browned). Does anything smell more appetising than cooking cheese and onions?


The Dear Leader (eternal damnation to those who oppose her) and Sternest Critic both approved, though both later blamed the need to extinguish naked flames in the house on the alliums.


The gratin is one of those culinary joys that seem to have been pushed aside as old fashioned - 'so eighties darling [bro?].' As someone who is a dedicated follower of anti-fashion I prefer, greedily, to keep it in my ever-expanding kitchen vocabulary. Perhaps restaurants avoid them as needing too much checking on, and for the time it takes, though as with the example above you can often pre-cook the vegetables and just need to slide the dish in a hot oven to finish.


It is also a great way of making something substantial that costs very little - especially economic if the oven is used for something else as the same time (the onion gratin was followed by a fish pie of modest size). Some years ago I wrote a paid piece for a culinary website where a cheesy potato gratin was one of (I think) four dishes to feed a family, each with ingredients costing under £2. No cream in that one then, but a stock cube, some dried herbs and a couple of cloves of garlic make a decent moistening, an alternative to milk, and supermarket cheddar browns as nicely as posher gruyere. You can save on pre-cooking too if, like in one cooked last week by Sternest Critic, you slice the spuds and onions to see-through thickness.


That use of vermouth, by the way, is something I'd recommend. I sometimes buy a cheapo bottle just for used in cooking - it gives a herby flavour, keeps better than wine, and makes you feel somehow more generous - as I only had some rather high end Dollin to hand, doubly so then. And its pairing with gin is as sublime as cheese with onions.
