Connie’s Notes

One of the five mother sauces in French cuisine, tomato sauce is so widely available that we cooks often choose convenience over texture and flavor.
The thing is, while commercial tomato sauce may cut down the cooking time, you also cut down on a lot of things.
  1. You pass off on the option to make a smooth or a chunky tomato sauce (yes, you have that choice!).
  2. You hand over to the tomato sauce manufacturer the freedom to determine how tomato sauce should be seasoned (there is only so much adjustment you can make with commercial tomato sauce).
  3. Most significantly, you give the manufacturer the right to put additives and artificial ingredients into your body.
It’s not difficult tomato sauce, really.
If you can boil, chop and stir, you can make tomato sauce.
You can also choose whether to use fresh tomatoes, canned tomatoes or passata.

Fresh tomatoes

There’s an easy way and a better way to use fresh tomatoes to make tomato sauce. 
The easy way is to dice your tomatoes and saute it with the required herbs and spices. Just let the tomatoes liquefy with plenty of stirring and the result is chunky tomato sauce.
The better way is to parboil the tomatoes so you can peel off and discard the skin. Just roughly chop, add to your sauteed herbs and spices, and season.
Parboiling and peeling tomatoes
Why is parboiling the better way? The tomato skin. Fussy cooks swear it can ruin the texture of the cooked tomato sauce. 
Con of using fresh tomatoes: The color and ripeness of tomatoes from the market vary. Sometimes, they’re all bright red and plump. Other times, they’re yellowish or even greenish, and the pulp has not turned soft yet. While all of these can be used to make tomato sauce, if the tomatoes are not the right color, add paprika and your problem is solved.

Canned whole or diced tomatoes

Canned tomatoes
Canned tomatoes come in at least two variants: whole peeled and diced. If using whole peeled, crush the tomatoes with your hand before pouring into the pot. If using diced, just pour the contents of the can into the pot. Cook as though you’re cooking with fresh tomatoes.

Passata

Not as common as canned tomatoes, passata is a Southern Italian tomato puree.

Passata is sold in jars. It is 100% tomatoes with the seeds, watery centers and skins removed. Only the luscious tomato pulp is cooked until it breaks down and liquefies. 

Chunky or smooth tomato sauce?

When you use fresh tomatoes or canned whole peeled tomatoes, you get chunky tomato sauce which you can easily transform into a smooth one by using a blender (immersion or traditional). Process to the consistency that you prefer. 
If using passata, the tomato sauce will be somewhere between chunky and smooth. That’s because you have bits of other solid ingredients like onion and garlic. You may smoothen the sauce some more also by using a blender.

My preferred method for making tomato sauce

First, I cook tomato soup with reduced amount of vegetable stock. (If I want a smooth sauce, I plunge in the immersion blender to smoothen the mixture) Then, I simmer it until it has reduced to the consistency of smooth tomato sauce.

Ingredients

  • 2 tablespoons olive oil - not extra virgin
  • 1 large yellow onion - peeled and thinly sliced
  • 4 to 6 cloves garlic - peeled and chopped
  • 1 sprig oregano - leaves only
  • 1 can diced tomatoes - 400 grams / 14 ounces
  • ½ cup vegetable stock
  • salt
  • ¼ pepper
  • 1 pinch chili flakes
  • ½ teaspoon sugar

Instructions
 

  1. Heat the oil in a pot.
  2. Spread the onion, garlic and oregano in the hot oil and saute, stirring often, until the onion slices and garlic are just starting to brown.
