Right, I've been making spag Bol for a while now as one of the few dishes I don't cock up. I've since decided to add in more veg (as it's not popular amongst the menfolk in my house) and it's all gone tits up.
The sauce is now thin and watery and very unappetising. I need to thicken it.
I have in the sauce a can of finely chopped tomatoes, 2 sticks of celery, a red onion, tomato paste, a carrot and a couple of cloves of garlic. I assume that the wateriness is from the veg.
So how do I make it thicker? I don't have the option of simmering for ages because of the DSs - toddler screams blue murder if I leave and the older one bounces off the wall. I want to get a slow cooker eventually, but cost is prohibitive.
