From BETH GREAR
Julie Johnson’s article about how microwave ovens fail to bring out
the flavour of food was interesting (New Scientist, Science, 18 January).
I would like to know what microwaves do to plain tap water. I have tried
once or twice to make a cup of tea with a microwave when a kettle was not
available. I heated water in the cup until it boiled and added a teabag
as normal. The tea was revolting, and nothing like tea made using an electric
kettle or a saucepan. What were the microwaves doing to the water?
