15-minute Spaghetti by Pavel Berky

Bring water to a boil in a large pot. Salt it (about 1 tablespoon of salt per 3 liters of water) and let it simmer gently while you prepare the sauce base.

Peel the onion and cut it into thin half-rings. Finely chop the garlic.

Heat olive oil with butter in a deep pan. Add the onion, lightly salt it, and sauté over medium heat until golden. Towards the end, add the garlic and sauté briefly, about 1 minute. Be careful not to burn it.
