It can be a bit tricky since not all recipes include weight. I was able to find weights for AP flour, sugar, and brown sugar. Now that I am making a switch to whole grains for baking, I will eventually have to find weights for whole wheat, and white whole wheat flour. Luckily "King Arthur Whole Grain Baking" uses weights.
To illustrate the benefit of using a scale, I conducted a little experiment. A cup of all purpose flour should weigh 4 3/4 ounces. I had Jim measure out 1 cup of flour (scooping out of the flour canister and then leveling off by sliding the knife across the measuring cup), I measured 1 cup of flour as I normally would in the past (same method as Jim), and I then measured 1 cup of flour using the scoop method recommended on websites and food blogs. This method tells you to fluff the flour, scoop it in to your measuring cup, and level it with the scoop.
Jims "cup" of flour weighed 5.3 ounces
My "cup" of flour weighed 4.6 ounces
My scooped "cup" of flour weighed 4.4 ounces
None of these weighed 4.75 ounces and my scooped cup weighed nearly one full ounce less than Jims.
Convinced? Give it a try. It really will make a difference in your baking.
Here is my scale. It was around $20. My recommendation is a scale with a tare function. This means you weigh your flour, hit tare and the scale goes back to zero. Now you can weigh the next ingredient in the same bowl. Keep weighing, taring, and weighing in the same bowl. One bowl is surely better than eight measuring cups to wash.
