May I interest you all in my homemade lunchtime sandwich?

[Burney]

I have fried some onions and garlic in butter, added assorted torn wild mushrooms and cooked down; then sliced taleggio on top, cooked until the cheese has melted and gone a bit crispy at the sies. This mixture was loaded onto thickly sliced sourdough. I considered adding diced pancetta, but felt this would simply be gilding the lily.

Yet another triumph for the open sandwich.

You ate it with a knife and fork, didn't you? That is not an open sandwich, it's mushrooms on toast. Quite different.
