i just steamed 4 eggs that were about a week old and they turned out perfect!!! i have a rice steamer that has egg trays, i did bump the steam time to 30 minute due to our altitude. i also will try fresh eggs the next time just to see.
so many techniques, and it seems some work for some and not for others. living here in Colorado i know you have to add time to the cooking due to the high altitude.
