Cooking is not just an art but science too. Any person who cooks should naturally be aware of the perfect colour, smell and taste that is to be expected from the product at various stages. Guessing the right amount of baking by colour and smell is definitely an art. But in order to get the desired result, it is necessary to look at the process scientifically and use appropriate measurements.
First reason to use scales in kitchen would be to get the desired perfection. While baking cakes or bread, correct proportion of ingredients is very necessary to get the desired taste and fluffiness. SO, kitchen scales are handy as ingredients can be rightly measured and added.
Secondly, recipes made according to cup or spoon measurements may vary each time as the cup or spoon may change. However, when ingredients are measured in grams or litres, there is little change of mistake or variation.
Third reason to use a kitchen scale would be that anyone can do the preparation provided proper measurements are provided. At least the basics can be taken care of even by novices.
Fourth reason to use a kitchen scale is that it is very handy, convenient to move and store and does not engage a lot of kitchen space.
The fifth reason is that kitchen scales are available in several user-friendly models. For weighing packets or bags, flat scales are available and for measuring liquids or flour, scales with bowls are also available. These facilities make cooking easy, convenient and perfect. Besides they are beautifully designed and easy to clean and maintain.
