I was a spoon and sweeper until I got my scale. I measured at least 5 cups of flour
I used the spoon and sweep method to fill the cup, and measured it each time. It always came out to 4 1/2oz, so now I convert my recipes with cup measurements to ounces, based on a 4 1/2 oz cup.
However, I do check the introduction in each baking book, to see what method they use. Sometimes I'll adjust, but most times I don't.
I've been using my scale for at least 4 years, and I used to convert each recipe, by scribbling the weight measurement on the side. Would have to bust out the calculator to figure out 2 1/2 cups multiplied by 4.5 oz per cup....)
Finally got smart, and created an Excel chart with all sizes from 1/4 cup to 5 cups. The chart is now taped to the cover of my flour and sugar containers - the flour chart is based on a 4.5 oz cup, and the sugar chart is based on a 7 oz cup.
I marked my other containers (powdered sugar, brown sugar, the corn syrup bottle, etc.) with the weight measurement for 1 cup, and I convert those on the fly.
Love love love my scale, and would recommend it to anyone who likes to bake smileys/smile.gif
