Boiling pasta in itself is easy - however, there's a problem I could never avoid or solve. When I judge the pasta is ready, I pour the unnecessary water out of the vessel, though even if I use a colander, the pasta keeps damp and moist, and even if I put it back to the fridge for a night or two, it keeps like that. Even adding salt and oil to the water did not help it.
What can I do against it?
