My sugo pomodoro (tomato sauce) doesn’t have any fixed amount of ingredients, however this is what I use basically... very useful for various recipes, I usually make some extra and keep it in the freezer...
(sauté these first)
(add these when the onion etc. are well sautéed, then let the wine get absorbed)
Tomatoes (if they are in season I like to use the fresh, ripe red tomatoes, but also the one from tins suffice just as well)
Basil (if I am using dried ones), Oregano, majoram, black pepper, salt
Cook for some 20-30 minutes
Add tomato sauce or puree, if you like your sauce thicker more of this and less tomatoes above, you may add some paste for this effect.
Cook to desired concistency.
If I use fresh basil leaves instead of dry, I add the chopped leaves at the end of the cooking.
