As you know every kind of pasta has a specific cooking time, that is,
7 minutes, 10 minutes, etc. : if we drain pasta according to the suggest of producer, a good pasta should be firm or better a little bit "raw", that is "al dente", which meaning is "a
little bit raw" when we taste it among the teeth (al dente = among
the teeth); however if we forget to drain pasta in time and
