Question: I lost my cup for measuring water for the eggs, how much water should I put for each type of egg?
Document: "You get:Poaching cups (not really poached, but you get a poached-like egg out of the shell, if you want)Measuring cup (graduated for the proper water level for each type and number of eggs)Piercing needle on bottom of measuring cup (releases sulfur and prevents yolk from discoloring)Rack holds 7 eggs.The good features:1. Flat profile. This fits on a narrow shelf in the cupboard because the top is not domed or bulky.2. Cord wraps around unit for storage.3.
Egg cooker? Put your eggs in a pan with water. Maybe they will come out like you want them. BUT, with this thing, you follow the instructions which take about 2 minutes to digest, prick holes in the eggs with the provided device,  put in the eggs, the measured amount of water (for which you are provided with a measuring beaker with markings for the type of boiled eggs and number of eggs) and turn it on. You can cook one to seven eggs at a time. When done, you will hear a loud alarm.
One drawback is that if I ever lose that little cylinder thing, I would have no idea how much water to put in for the type of egg that I wanted. Also, you there's a "keep warm" setting on the cooker. However, if you want your eggs to remain a soft boiled, you can't really use it, because the egg will just continue cooking. But overall, I think that this egg cooker is great and I haven't seen anything else like it.
The measuring cup clearly tells you how much water to use. The amount of water you use determines how well the eggs are cooked. When the eggs are done (apparently when the water is all evaporated) a buzzer sounds and you need to turn off the unit, take the egg tray to the sink, remove the lid, and spray cold water on the eggs.I don't normally eat poached eggs, but I tried it out once to see how it worked. The insruction booklet tells you what water amounts to use for a "4-minute" egg and a "5-minute" egg.
This was easy to use after you figure out how to read the water cup. We have enjoyed our eggs very much. I love to cook them hard boiled for using later. Just start the egg cooker, do other things in the kitchen and turn off the egg cooker when it buzzes. They are hot so be careful getting them out with a spoon and put them out to cool.
When I was growing up my mom used to make me soft boiled eggs with torn up pieces of bread in them.. The bread would soak up the yoke. Now that I'm 57 yrs old, I discovered this GREAT EGG COOKER! I put 4 eggs in the cooker, put filtered water from the faucet into the measuring cup for soft boiled and when it buzzes.. they are done perfectly.I have cooked hard boiled, medium and soft and as long as you use the right amount of water, they come out just right!
When the S.O. got one of these I was more than skeptical, I thought it was down-right silly. If you can turn on the stove and set a timer you can make hard boiled eggs, so why would you need an electric egg cooker? !After using the Krups Egg Express Egg Cooker, I was converted into a believer, here's why:It's faster than boiling eggs on the stoveIt doesn't heat up the entire kitchenThe eggs are perfectly cookedEgg cracking is extremely rare (much less than boiling)and believe it or not, the eggs always peel much easier!The holder picks up all the eggs at once, no need for tongs.The recessed area at the bottom take care of cord storage, and the measuring tube stores inside the holder.It is so easy to use, put up to 7 eggs in the holder, use the pin on the recessed end of the measuring tube to pierce the shells, add water (measuring tube is marked for # of eggs and degree of hardness) turn the knob to the right and in a short while the bell dings and that's it.It's been a couple years now and it still works great.
This gadget really is a bargain at $20. FYI from previous review(s), the manual is INCORRECT showing the (POINTED) end of the egg being punctured (illustration #2) DO PUNCTURE THE ROUND END and you could prevent a mess. Every function worked as described. Owners should probably convert the measuring beaker capacities into fluid ounces or mL using a measuring cup should it become lost or broken. If it had an automatic shut-off feature I would have rated it 5 stars. Remember to allow yourself adequate time for cooking, this is a product that should NOT be left unattended while using.
For soft-boiled eggs I just fill up the provided measuring cup to the line indicating soft eggs and number of eggs I'm cooking, use same cup to pierce the eggs with the pin that is in one end of the cup, place the eggs in the cooker, place the lid on, turn the dial to the right to cook, and wait for the timer to sound. I take the eggs out immediately to take them out of the steamey/hot cooker to keep them from continuing the cooking process. I put them in their egg cups and serve.Hint:  I like really soft-boiled eggs so I use the line on the provided measuring cup for one less egg than I actually have.
My family all love hard boiled eggs/egg whites and this is the easiest way to make them. Put 7 eggs in, add the water for the Type of egg you want (soft boiler, med or hard boiler) turn the timer. It takes about 10 minutes and they are perfect every time. My Dad got me mine and then I got a friend of mine one. I love it.
Answer: I would contact Krups too; however, I did measurethe quantities for hard-boiled only since you didn't specify which ones you wanted.  These are approximate:  7 eggs=1/4 c + 1tbs + 1 tsp; 6=1/4 c + 2 tbs + scant extra; 5=1/4 c + 1 tbs + 2 tsp; 4=1/4 c + 3 tbs; 3=1/4 c + 3 tbs + 3 tsp; 2=1/4 c + 3 tbs + scant extra; 1=1/2 c.  My good deed for the week.
