CRACKED! Soft, Medium, and Hard "Boiled" Eggs in the pressure cooker


I would never recommend pressure cooking something unless this cooking method improves the food or recipe in some way. For example, I didn’t publish a pressure cooker frittata recipe – it takes twice as long as the original, discolors badly, and acquires a rubbery consistency – not an improvement (flans, on the other hand, are divine)!You can imagine my suspicions about making hard-boiled eggs in the pressure cooker, given that there is no time savings.

The real magic of pressure steaming an egg in the pressure cooker is the ability of using FRESH eggs and getting easy-to-peel hard boiled eggs – instead of old, musty 7-10 day old eggs!  The result looks better, tastes better and is totally worth pulling out the pressure cooker to do.

An innocent blogger peeled away the mystery by noting a little technical tidbit he uncovered in a book:

Per Jeff Potter in Cooking for Geeeks pg. 183, eggs that are hard boiled commercially are steamed at 7.5 PSI for ease of peeling.

This blogger was great at connecting the dots but not very clear with his

methods so, armed with resident 5-year-old egg-spert Vittorio, lots of eggs and inspiration from online previews of the scientific culinary epitome, Modernist Cuisine, we set out to perform our own experiments.

Even though the pressure cooker was invented at the end of the Renaissance (1679), it’s a cooking appliance that has become a must for any Modernist, or in our case, hip cook!

The style of this “recipe” might be a little different than what you usually find here, since it was heavily inspired by the aforementioned, book. Even the step-by-step photos are not immune, featuring our most beaker-like containers and surgical-looking tongs!



“Hard Boiling” Fresh Eggs
Why are fresh hardboiled eggs so difficult to peel? Eggs have an air cell at the wider end of the egg, between the shell and the white (albumin).

When the egg is freshly laid this air pocket is very small and only located at the bottom – the rest of the white remains in close contact with the shell.  If a fresh egg is boiled using conventional cooking methods and peeled, much of the white will come away with the shell in uneven chunks leaving an unattractive hard-boiled egg. Culinary experts recommend aging an egg for at least  week in the refrigerator prior to boiling to achieve an easy peel.

Aging the egg increases the air pocket to include the areas around the whites creating a distance from the shell that results in an easy peel. Unfortunately, as the egg ages, the size of the air cell at the bottom also increases resulting in a hard-boiled egg with a flat area in the whites, reducing the quality of the egg and negatively affecting the color of the yolk.

Pressure Steaming A Fresh Egg
Steaming a fresh egg at low pressure, creates a pressure difference between the exterior of the egg and the air pocket – inflating it and separating the white from the shell. Making a pressure steamed fresh egg, easy to peel.

When we are referring to low pressure we mean 6 to 8 PSI (40 to 55 kPa, or .4 to .55 Bar). Pressure steaming an egg at higher pressure, will result in the cracking of the shell prematurely, causing the whites to ooze out and be immediately cooked as they exit the shell – resulting in an unattractive, but still very usable and easy to peel egg.

Pressure Cooker Hard-boiled Eggs
 
Author: 
Recipe type: pressure cooker
Prep time: 
Cook time: 
Total time: 
See above table for exact cooking times for both stove top and electric pressure cookers. The same procedure and cooking times can be used for up to 6 soft and medium-boiled eggs or as many hard-boiled eggs as can comfortably sit in the steamer basket.
INGREDIENTS
  • 1-6 XL Fresh Egg, chilled (from the refrigerator)
INSTRUCTIONS
  1. Fill the cold pressure cooker with one cup of water. Add the steamer basket, or trivet and steamer basket, egg stand and egg.
  2. Close and lock the pressure cooker. Set the pan to cook on LOW pressure. Turn the heat up to high and when the pan has reached LOW pressure, lower the heat and count 3 minutes for soft-boiled, 5 for medium boiled and 6 minutes cooking time for hard boiled eggs.
  3. When time is up open the pressure cooker
    ......for soft and medium boiled eggs, use the Quick Cold Water Release - bring the pressure cooker to the sink and run cold water over the top without obstructing valves to bring the pressure down quickly.
    ...for hard boiled eggs, use the Natural Release method - move the pressure cooker to a cool burner and wait for pressure to come down naturally (about 5 minutes). If in 5 minutes the pressure has not released the lock on the pressure cooker, release the rest of the vapor through the valve.
  4. Open the pressure cooker and place the egg(s) in a container under cold running water, for about 1 minute if you would like to serve them warm, and 3 minutes to cool down completely.
  5. Tap the two ends of the egg on the counter-top to crack, peel to remove the shell.

Special Equipment: Heat Proof Egg Stand
Although poaching pans for the pressure cooker are readily available. Egg-stands for pressure steaming eggs are not – they do not exist! We found an Olive Oil Cap (with the plastic insert removed) to be the perfect heat-proof,  food-grade egg stand to be used in the pressure cooker.

NOTE: Children can assist in the preparation of pressure cooker but should not be involved in the cooking, monitoring and opening of the pressure cooker.
