This procedure I got from America’s Test Kitchen, who developed it so that they could reliably soft-cook a single egg or a dozen. It relies on the temperature of steam to cook the egg(s) and the quick recovery time of a shallow batch of water when a variable number of cold eggs are introduced into the mix. They recommend five and a half minutes, but even with jumbos, I prefer 5:15. They also use a saucepan or somesuch, while I use a skillet with a tight-fitting lid. I think that they want a taller steam area, but I find that the shallow steam bath works just fine for me.
- Choose a cooking vessel with a flat bottom that is large enough for the number of eggs you want to soft cook to fit lying down with lots of room around them. It doesn’t matter if the sides are straight or sloping, so long as the flat area works and the lid is relatively secure. I normally use a Le Creuset 6" skillet, which has pouring spouts that leak steam, and it works fine so long as I cover it. I can’t think when I have ever cooked more than two eggs this way, so the small size works for me.
- Put in enough water that it will come about halfway up the eggs you are going to put in later.
- Cover (so that everything in the equation gets nice and hot).
- Bring the water to a boil.
- Reduce heat to a vigorous simmer.
- Carefully but quickly add the cold eggs.
- Recover and watch to make sure that the steam starts running out the top again.
- Set a timer for 5¼ minutes.
- Carefully drain and run cold water over the eggs.
- Put the eggs into cups, open the tops, and enjoy!
