Start both timers at the same time, when the 3 minutes one end turn it. When the 5 minutes one end turn it and put in the 2 eggs. This will leave 1 minute on left on the 3 minute timer. When the 3 minute timer ends again, turn it. When the three minute timer ends again take out the first egg and turn the 3 minute timer. When the 3 minute timer ends the second egg will have been in the water for 7 minutes. Take it out.

Total cooking time : 12 minutes.


Another method could be :
Start both timers at the same time, when the 3 minute timer ends put in the first egg and turn the 3 minute timer. (2 minutes left on the 5 minute timer).
Wait for the 5 minutes timer to finish and insert the second egg (1 minute left on the 3 minute timer) and turn the timer over.
Turn the 3 minute timer over after it finishes.
Turn the 5 minute timer over and take out the first egg (the first egg should be in the water for 7 minutes.
When the 3 minute timer ends take out the second egg.

Total boiling time : 10 minutes.

Hope this makes sense, though probably doesn't :).

Put both timers on with no egg in when 3min timer goes off put first egg in and reset 3 min timer. This gives two more minutes on 5 min timer.

When the 5min timer goes off reset it to get another 5 min, there will be one minute left on the 3min timer when this goes off put other egg in, there will be now be 4 min left on 5 min timer.

The 5 minute timer running twice gives total of 10 minutes, by running 3 minute timer you can time when to put eggs in, once after 3 minutes and once after 6 minutes. taking this from the total 10 minutes gives 7 and 4

Start both timers.
When the 3 min one is up there will be 2mins left on the 5min one. Turn the 3min one and when the 2 mins left on the 5min timer is up there will be 1 min left on the 3min timer.

Put both eggs in the water. When the 1 min is up turn the 3min timer and after 3mins take one egg out (4 min egg) and turn the timer ..after 3mins the second (7min egg) will be done....enjoy.

according to this site I looked up, a perfect boiled egg is hardened in 5-6 minutes. Over cooking will result in the shell to stick to the egg. I looked this up last week as I couldn't understand why my shells were sticking! Boil both eggs together and use only one timer.

you follow this procedure

start both timers

when the 3 minute one ends, start it again and add the first egg to the pan

when the 5 minute one ends start it again

when the 3 minute one ends for the second time add the second egg to the pan

after the 5 minute timer finishes for a second time then both eggs are done, one for 7 minutes and the other for 4 minutes.

Set the five minute for four, set the second timer the second the five minute goes off, fast get four minute egg off heat.
Not pretty but fool proof.

15 minutes
Make sure you put them in cold water so the shell comes off easily.
