Continue to cook the sirloin roast until a meat thermometer registers 130 degrees at the CENTER of the roast for medium rare at the center, medium on the ends. This should take around 20 â 30 minutes per pound, but never rely on exact times. Use a meat thermometer instead.
Storage: Keep the box because unused phyllo dough can be refrigerated or refrozen. You can wrap any leftover phyllo tightly with plastic wrap, place in its original box and keep in the refrigerator for up to 2 weeks. For longer storage of up to 2 - 4 months, refreeze phyllo.
Best Answer: most leftovers are good for 3-4 days, tops. i definitely would just toss it and make some more. it does last way longer if you freeze it. sometimes when i have lots of extra pasta sauce, i freeze it in ziploc bags. the bags make the sauce super easy to defrost and use.Source(s):irish_3078 Â· 9 years ago.est Answer: most leftovers are good for 3-4 days, tops. i definitely would just toss it and make some more. it does last way longer if you freeze it. sometimes when i have lots of extra pasta sauce, i freeze it in ziploc bags. the bags make the sauce super easy to defrost and use.
