Weighing and measuring

You’ll notice that everything in this book is measured first by weight, and secondarily by volume. This is for accuracy and consistency. Depending on how much it is compacted, quantities of flour and other dry ingredients can vary hugely from cup to cup, and a jug at a slight tilt can lead to the amount of liquid you think it contains being way out. The cup measure of a starter will also vary depending on how active and bubbly it is. I suggest buying electronic kitchen scales and getting comfortable with metric weights.
