Very finely slice an Onion
Heat a pan with lots of Olive Oil and gently fry the sliced Onion for 10 or 15 minutes, stirring lots so they don’t catch, but for long enough that they go super soft, sweet and delicious. Season with Salt & Pepper
When they are really caramelised, add a tablespoon of Plain Flour – maybe a bit more. Stir, and make sure all the Flour is soaked into the Oil and the Onions…. Cook for a minute or two, stirring and then add the Marsala….
The Gravy will thicken, but this is OK… just cook for a minute, still stirring, and then add a mug of Stock (preferably homemade, will definitely taste much more delicious)
Stir and gently simmer until the Gravy starts to really look like Gravy… you might want to reduce it a little, or to add a little more Stock (or water)
Add the finely chopped Herbs; Sage, Thyme and Parsley (or any combination thereof) a few minutes before serving (the Sage will need to cook a little so it’s at its best)
