The perfect Ragu sauce. 20-odd years ago I was trained at cooking school and subsequently worked part-time at a couple of Italian restaurants.
Hands up, many people add sugar to their spagbol or lasagna? Over the years I've perfected the Ragu without additional sugar. You'll need:
Large onion
Celery
Carrots
Balsamic vinegar
Tomato puree
Tomatoes
Red bell peppers
Method:
Under a screaming hot grill, blacken the peppers. Once charred cover in cling film or tin foil and set aside.
Soften the celery and carrots in good quality olive oil, then add the chopped onion and cook very slowly. Onions naturally have a high sugar content and slow cooking brings the sweetness out without colouring. Once soft, add finely chopped garlic and add the tomato puree (important you add the puree before adding the tinned tomatoes. Puree is quite bitter) with a good glug of balsamic vinegar - only for about 30 seconds. Season with black pepper and sea salt.
Don't buy the chopped tinned tomatoes. The whole plum toms tinned are of better grade. You can also use fresh and vine tomatoes.
Optional: You could use fresh herbs, but not essential at this stage.
Remove the peppers from the foil or clingfilm and scrape some of the outer blackened skin off.
Add the Ragu and peppers to a food mixer until smooth. You can refrigerate or freeze the Ragu sauce, and it can used in a plethora of dishes, including Chili con Carnies
