Bring water to a boil in a saucepan. Meanwhile, prepare a water bath with ice cubes and scratch the tomatoes four times from the stem down with a knife. As soon as the water boils, put the tomatoes in for a short time and then immediately put them in the ice cube bath. Now you can easily remove the skin, should it not be so easy, just put the tomatoes in the boiling water again.
When the skin is off, remove the stalk and roughly chop the rest. Peel and chop shallot and garlic. Heat the olive oil in a saucepan, then sweat the shallots and garlic in it. Add the sugar. As soon as this has dissolved slightly, deglaze with balsamic vinegar. Then immediately add the diced tomatoes. Season with salt, pepper and cayenne pepper. (Don`t be afraid of so much salt, sea salt tastes better, but has less salt than normal salt.) Let everything simmer for about half an hour.
Pluck the rosemary and oregano from the stalk, chop finely and add to the sauce.
Now the spaghetti can be cooked. When these are ready, pour off the water, save some of it and put it back in the pan with the pasta (this will prevent the spaghetti from sticking so easily).
I always prepare the spaghetti as a nest in a deep plate, then I put the tomato sauce and a few basil leaves on top. It tastes particularly fine if you add a few splashes of olive oil and old balsamic vinegar to the sauce.
The Boss Kitchen editorial staff oversees content review, fact-checking, and recipe verification across the site. Published articles pass through the editorial team before going live, ensuring ingredient lists, techniques, cooking times, and nutritional claims hold up in a home kitchen. The team coordinates contributions across the site writers, handles reader corrections, and maintains consistency in measurement conventions, safety guidance, and dietary labeling. Posts under this byline typically represent team-reviewed reference material, site announcements, or editorial roundups rather than individual-author features, and they are held to the same sourcing standards as bylined recipe and product coverage.
