Measure the amount of pasta
Who does not know that: The pasta water cooks, but now fast, noodles in. As? Best of the pack. Scissors, ratz fatz and schwuuuuuup purely with it. Oooops, accidentally I slipped too much. Reaching out does not work. Crap.
Do better: Put the pasta in the sieve first, which you need anyway later. In it you can estimate approximately what you need. In addition, it can also be better (for example, spaghetti) estimate how much you need.
