This was a little too salty for my taste, but not too bad. Maybe the Stock Pot was a mistake....
2 large onions, chopped (mine were not as chopped as I should have liked, as I was going to do them in my mini food processor, and it was totally discharged)
A little sunflower or other vegetable oil
1 Stock Pot (I used beef, as we were having it with Cornish pasties, but chicken or veggie would work, it depends what you want to eat it with)
1-2 tsp plain flour (use cornflour or a gluten-free variety if you need to)
1/4 cup cold water and 1/2-2/3 cup boiling water
Seasoning to taste - I used a bit of vinegar and some black pepper. I had salted the onions, but wished I hadn't!
Put a heavy-based pan on the stove and let heat up, and add the cooking oil after a few minutes. Then put in the chopped onions, stir, and turn the heat as low as it will go. I think I should maybe have used a different burner, as mine caught slightly rather than caramelised nicely. Cover, and leave to cook for 30-45 minutes, stirring occasionally.
Then stir in the Stock Pot (if you are using a cube, dilute it in the boiling water). Put the flour in a mug and add the cold water (quantities need not be exact), and stir, then stir this through the onions, and finally add the boiling water. Now season to taste, and then leave on a low heat, uncovered for a further 20-30 minutes until it has reduced and is lovely and thick!
I was making chips in my air fryer, and thought afterwards I could have turned this into a curry sauce by adding a spoonful of curry powder to the oil before anything else, and then using a stick blender on it at the end. Next time, maybe.
