Yes, it may seem like a silly recipe.
But this is part of a campaign to get people to ditch those horrible store-bought sauces and the homemade ones that taste like ketchup.
It's basic, quick and you can use it for any cuisine just by changing the spices.
Do yourself a favour. Throw out any ketchupy stuff, any recipes that lead you to make that, and if you already make good tomato sauce, send this on to your friends who need it.
Note: These are the basic ingredients. I don't know any real proportions, but as long as you don't chuck in something like 2 onions, 4 cloves of garlic and one tomato, you'll be alright.
1/2 - 3/4 large red onion, peeled and finely chopped
1-2 clove garlic, peeled and finely chopped
Around 3-4 Tomatoes, washed and chopped (you can peel them if you want by first soaking them in hot water)
Olive Oil/ Canola, sunflower or vegetable oil
Italian: Take your pick, or put all 3 (Fresh or dried) Basil, Oregano, Rosemary
Indian: Garam Masala, Turmeric powder, cumin powder, coriander powder, mustard seeds (optional), fenugreek seeds (optional)
Plain: Salt n' Pepper
Heat some oil (If you're using fresh rosemary, fenugreek seeds or mustard seeds, add them in now. Let the seeds cook and, if possible, let the mustard seeds pop. But don't let them burn!) in a large saucepan and add your onions. Cook until they're lightly coloured. Add your garlic and cook for another 1-2 minutes- keep watch because it burns quickly.
You can either purée your tomatoes or leave them diced, depends on what texture you wand and how picky your eaters are. The same applies for the cooked onions-garlic mixture. If you want to purée it, add it to the food processor with the tomatoes.
Add it back into the saucepan with a few dollops of tomato purée, stirring as you add until you get the desired colour. Cook until it's boiling. Season with salt, pepper, the dried herbs or the remaining Indian spices.
