On my pasta package it says something like ready for double cooking and more curiously it gives cooking times of 11 min for regular (single cooking) and 5.5 / 2 min for first/second cooking when double cooking.
I had never heard of this double cooking before. In case it matters, this was on a large 5 kg package of pasta.
What is double cooking and why would I want to do it?
Is it something restaurants do?
Why is the total cooking time for double cooking (5.5+2=7.5 min) shorter than the regular cooking time (11 min)?
Is there anything special about this type of pasta or could any pasta be prepared like this?
