After Goldilocks had eaten the bears’ porridge, she decided to make coffee.
The first time she boiled the kettle and poured it right away, using water that was too hot. “Oh!” she cringed, “this coffee is bitter.”
So she made more coffee, without heating the water again. This time it was too cold. “Oh!” she said, making a disappointed face, “this coffee is sour and weak.”
The third time she heated the kettle to a boil then let it cool for just under a minute before she poured it. “Ah!” she sighed, sipping her java contentedly, “this coffee is just right.”
And that’s all you need to know.
You don’t need to spend hundreds of dollars on an expensive kettle. But you can if you want to!
