Glamorgan Sausages with Mash and Onion Gravy

There's a kind of November evening, dark by half past four, rain finding the kitchen window, when what you want is something golden and crisp on a warm plate with a pile of mash and a gravy that has taken its time. This is that supper.

Glamorgan sausages have nothing to do with meat. They're Welsh, and older than rationing, though it was wartime thrift that brought them back to kitchen tables across the country. Cheese, leeks, breadcrumbs, a smear of mustard, shaped into fat little sausages and fried until the outside goes crisp and the inside stays soft and yielding. Caerphilly is the proper cheese. Its crumble and sharp tang are the character of the thing. If you can't find it, a good Lancashire or crumbly Cheshire will stand in honestly.

The mash wants to be plain and generous: real butter, warm milk, enough salt. The onion gravy is the quiet centre of the plate. Three or four onions, cooked so slowly they go from sharp and pale to sweet, dark, and sticky, then loosened with stock into a proper gravy. The whole thing comes together in about an hour, and most of that time is the onions doing their work without you.

I wrote it down in the notebook once: leek sausages, mash, gravy, rain. That was enough to bring the whole evening back.
