Do potatoes get hard when overcooked?
Did you have a particular question? Hard potatoes usually result when the cooking temperature is not high enough to soften the starch in a potato. Usually that combination happens in an older style of slow cooker which does not have a very high temperature setting.
What is the white foam when boiling eggs?

This is called foaming and it is caused by high concentration of any solids in the boiler water. It is generally believed, however, that specific substances such as alkalis, oils, fats, greases, certain types of organic matter and suspended solids are particularly conducive to foaming.
Why do boiling potatoes foam?
Foam is generated from the starch and protein interacting with the water. This is because starch is released into the water during the washing and slicing processes of potatoes, creating a foamy mess.
Why is my pasta water foaming?
It’s the starch molecules that are important. Once they’re heated in a moist environment—like your pot of water—the starch will absorb more and more water until it finally bursts. That sends little starch molecules into your water, resulting in white foam. … This makes the starch molecules heat up very quickly.
How do you stop potatoes from foaming when boiling them?

What can stop an egg white from foaming?
Sugar is often added to egg whites when making meringues and other desserts. It is important to add the sugar correctly to preserve the integrity of the foam. Sugar must be added gradually to prevent collapse, so begin with a small amount once the egg whites are foamy, and continue to add it gradually as you beat.
Do you put eggs in cold water after boiling?
After boiling your eggs for 10-12 minutes, put them in cold water to bring the temperature down rapidly and stop the cooking process. You can even use ice cubes in your water, and you can change the water as it warms.
How do you tell if hard boiled eggs are bad?

Do hard boiled eggs need to be refrigerated?
Refrigeration is key to keeping your hard-boiled eggs safe and fresh. Hard-boiled eggs should be stored in the fridge within two hours of boiling and kept on an inside shelf instead of in the door. Avoid peeling hard-boiled eggs until you are ready to eat or cook with them.
Why do you remove foam when cooking?
