Just ran across this...tried it...and...it worked! Cover eggs with cold water. Add 1/2 tsp. salt and 2 Tblsp. vinegar (white or cider...doesn't make a difference)...bring to a boil and let boil one full minute....take off stove and cover with lid...let sit for 20 min....THEN...pour off hot water ...put under the faucet and run cold water on them for at least 3 minutes...crack smaller end first then roll on counter...peel!
Have done this 3 times now and worked perfectly all 3 times.
Good luck!
