Most supermarket pastas..spaghetti, conchiglie, etc. state 10-12 minutes cooking time. Well, I know the difference between undercooked, Al Dente, and overcooked, but even with a very fast boil, I find that most brands need 15 minutes to be perfect. Very hit and miss........comments?
I always find that, whatever the product, the printed cooking times always err on the lower side ...perhaps to avoid a complaint to manufacturer/supplier that the instructions resulted in overcooking the item concerned.
To answer you question,....I go along with both Toldyso and wolfgang.
It doesn't matter if it is' fast boiling' or 'slow boiling', water boils at 100 degrees c and doesn't get any hotter because it is boiling faster. That said, 12 mins will do it.
I accept that fast boiling water may help prevent the pasta sticking. However since the thread was about pasta cooking time i pointed out that fast boiling water wouldn't make it cook any faster. Unless of course all the pasta stuck together in a huge lump because it wan't moving around enough, then of course it would take longer. But that never happens ( or not to me anyway).
the suggestions of a touch of the olive and tasting are the best ones....ignore the recommended time to some extent......and I hate wallpaper paste soft pasta - al dente for me pls...
Whether one uses fast boiling water, soft or hard water, cooked in white wine etc,etc. it is my opinion that the best advice was given at the very start of this thread....."just test it" as I do; and I put it on to simmer when boiling point has been reached. It never boils over and messes-up the top of my stove.:-)
Comments about the too-short cooking time shown on packets of pasta have been going on for many years. The conclusion seems to be that the manufacturers want you to believe that it won't take long to prepare. Experience shows them to be wrong, but they still keep doing it.
