Hello

Because when some things reach boiling point they start to react differently with the other elements around them and can change the taste. In addition you lose more water making it too thick.

Having said that, I usually manage to mess up "cooking" soup and it tastes okay to me.

I don't think I've ever managed NOT to boil soup, unless it's the cup-a-soup version.

Absolutely, you see it's the 'flavour particles' reacting with elements of the 'heat particles' that result in the taste being affected in some way...



... Hope this clears it up for you REV

At a wild guess from my university days I would say its because the water molecules start to change their state from liquid to gas at boiling point and also start to get quite "energetic" which probably means that water molecules in food start to break out violently and altering the composition/structure.

Also soups with milk/cream will curdle if boiled.

Well I boiled my beef broth (although where do you draw the line between a brisk simmer and a boil?) and it still tasted good

Anything cooked on simmer will contain more flavour (of what you really want!)
Anything cooked on High will give it a "smokey" flavour.This is my excuse to serve burnt food to people when I have cooked in a hurry.It just has a "smokey" flavour!

The proteins in the soup are a particular shape at room temperature. The distinctive curled up shapes of these proteins have active areas that are recognised as particular flavours by the olfactory (smell-sensing) system. The proteins are held in these shapes by chemical bonds and the shape is unique for each kind of protein. When a protein is heated up it shakes more and more violently until at about 60 or 70 degrees Celsius and greater, these weak bonds begin to break and the protein "pings" out of shape; the shape of the active site alters and the flavour detected is different. This is called "denaturing".

Not sure about soup but pouring boiling water on coffee will kill the taste stone dead, always warm the mug first then put the cold milk in the mug then you are ready to pour the boiling water, if you think im talking bull try it!!

why do you thing coffee perculators only heat the water to 80 degrees
