It also helps (a lot) if they aren't the "freshest" eggs. Our neighbors
have a couple dozen chickens that produce way more eggs than they can
use, so we get to share the bounty. The really fresh eggs that are only
a few days old or less will not peel worth a hoot if you boil them. They
will peel much easier if they are a couple weeks old. It has to do with
the membrane between the shell and the egg. white.

Made some more eggs last night. Very hard to peel.
Had to go back to find this bit of research to see what I did wrong.
So, drop them in boiling water with vinegar and salt helps them to be
easy to peel.
Last night I put them in cold water and brought it to a boil.
So I did the worst method.
Maybe I need to make myself a note about this and paste it in the fridge.

5 saucepans and 1 pot.
6 burner Comstock Castle restaurant stove.
24,000 BTU per burner.
1 quart of water in each.
A bit of variability in pan sizes.
All eggs from same carton. Cold refrigerator temp.
4 Variables
C/H Cold Start/Hot Start
W Plain Water
V Vinegar only added
VS Vinegar & Salt added
V = 1/2 cup distilled
S = 1.5 TB
Count starting with top left burner CCW around cook top.
1 CW
2 CV
3 CVS
4 HW
5 HV
6 HVS
In the photo of the cut eggs the order from left to right is 123654
Salt and Vinegar boiled first which seems backwards to me. Freezing point
depression, boiling point elevation of solutions.
I suspect it had to do with nucleation sites.
Water boils at 204 at this altitude.
HVS boiled at 206
W boiled at 202
HV boiled at 208
Took a full 9 minutes to hit a full rolling boil.
Cooked the Cold start eggs 18 minutes total. Heat off at 9 minutes.
Cooked the Hot start eggs about 14 minutes boiling and another 2-3
with heat
off.
Single blind study. Wife peeled and rated.
Rated ease of peeling on 1-10, with first egg arbitrarily assigned a 5.
1 CW 5 Peeling came off in large pieces, egg broke during
peeling
2 CV 5 Broke egg
3 CVS 5 Broke egg
4 HW 6 Peeling came off in sheets
5 HV 6 Peeling came off in sheets
6 HVS 7 Peeling came off in sheets
1 & 4 were cooked enough for me. All the others had a dark yellow
slightly
wet interior to the yolk.
So, it appears that placing them into a rolling boil kept the egg more
structurally sound, helped the peeling come off in sheets.
Vinegar and Salt appears to help the peel detach.
I think I would up the cook time to at least 15 minutes rolling boil
with a
few minutes to soak after the heat is off.
