I've found that weighing ingredients makes a huge difference in my baking, so I've added a digital scale.

This simple scale zeros out easily, and its maximum capacity of 11lbs pretty much ensures I won't need something larger.

When baking cookies, bread or cakes I've found that simply scooping ingredients via cup measure, or measuring spoon, and result in some pretty large differences when compared to weighing out exactly the amounts called for.

Here is an online calculator to help you convert volume based recipes to weight, if you'd like to try. I have found cooking by weight makes for a more consistent product. I have an easier time getting chocolate chip cookies just like I want them.
