Yes! I have learn't through experience that weighing ingredients using a scale whilst baking is super important and will allow you to reproduce great results every time! I've attempted measuring out the flours by volume (e.g. cups), then double checked the weights of each. They were off by quite a lot actually! It can mean the difference between the most incredible and beautiful looking bagel, to one that quite literally flops. The density of the ingredient makes a BIG difference in the volume of the flour. A new bag of flour may be packed down tight vs an already opened one. A gram will always be a gram of flour!
A KITCHEN SCALE IS WORTH THE INVESTMENT
