You need a big pot, plenty of water, coarse salt and a timer. Oil is useless in the water, it floats on the surface. What keeps pasta from sticking is having plenty of water and stirring once or twice at the start. For the rest, the timer works for you.
Taste a piece of pasta one minute before the time on the packet. It should be tender, with a tiny bit of firmness left in the centre. The packet time is a guide, not a rule.
Count 80 to 100 g of dry pasta per adult, and 60 g for a child. It doubles in volume as it cooks.
Fifteen minutes, ten of which the water heats and the pasta cooks on its own.
Overcooked, it will be very good as a gratin tomorrow, with a little cheese on top. Stuck in a block, a little hot water and you stir, it comes apart. Not salty enough, salt the sauce a bit more, it catches up on the plate.
Pasta with butter and parmesan, in twelve minutes, if you are starting out. Or the grandma-style bolognese sauce, if you have an hour ahead of you.
