I get perfectly boiled eggs every time - eggs from the Fridge, fill the pan with cold water so they are just covered, put on the gas at maximum for nine minutes.
Obviously, I didn't know where Jennyjoan kept her eggs and many people do keep them in the fridge. My advice...and Delia's...was simply to ensure they were at room temperature.
One egg at room temp.
Place in a small pan (like a milk pan)
Cover with cold water but just enough so the egg is not completely submerged.
Place on a high heat and as soon as the water boils time it for 3 mins exactly. Remove from pan and open immediately. This is important as otherwise the egg will continue to cook under its own steam, thus giving you a hard yolk.
I agree with Obiter, heat the water from cold and then 3 minutes when boiling. Then under the cold tap for 10conds or so, to stop the cooking process, then eat with homemade wholemeal toast. Had a look at the timer recommended by 2sp and bought one to try. Well it was only £1 inc postage so will give it a try.
