How to avoid cooked pasta soaking up sauce when stored?
If I plan on storing my pasta in the fridge with the sauce, I take the pasta out of the boiling water and immediately rinse it in cold water. I rinse until the pasta has cooled completely. Make sure to drain it well. Afterwards, I either mix a little sauce in the pasta to help keep it from sticking or just put the sauce on top.
Basically I'm trying to stop the pasta from continuing to "Cook" in the sauce.
