Prevent extra cooked pasta from hardening by stashing it in a sealed plastic bag and refrigerating. When you're ready to serve, throw the pasta in boiling water for a few seconds to heat and restore moisture.
You can freeze cheese! After serving, put leftovers back in the original package, wrap tightly in plastic, and freeze. Defrost in the fridge a day before serving. This trick works best for soft cheeses with a high fat content. - GoodHousekeeping.com
