Everybody has their own take on a spag bol. Here's mine...
500 lean steak mince
2 cloves of garlic (or a good squeeze of the tube)
1 tin tomatoes
1 carton passata
smidgen of tomato paste
salt & pepper
Chop the onion, if you're using fresh garlic then peel and crush the cloves. Fry the onions with the garlic. When they've softened add the mince. While the mince is browning peel and chop the carrots and then add to the pan. Add the tinned tomatoes to the pan and allow them to cook off. While that's happening chop the mushrooms.
Ideally use a bigger pan than I did....
When the liquid from the tomatoes has cooked down a bit add in the mushrooms and the passata, then lastly the puree and some herbs, and finally some salt and black pepper. I tend to use dried mixed herbs, and then if I have it I serve with fresh basil.
I let my bolognese cook for as long as I can, the longer it cooks the better the flavour I find.
Sometimes I crumble a beef oxo over it, to add more depth. If I haven't used carrots then I sometimes add some Worcestershire sauce to sweeten it.
Now I know some people brown their mince then remove it and cook the onions, but I can't usually be bothered with doing that.
How do you do your bolognese?
