It didn’t take long for me to realize that my new measuring cups for dry ingredients weren’t giving me accurate measurements. These were part of a large line of baking utensils from a very famous celebrity baker, but when I tested the cups for accuracy, I discovered that the one cup measure actually held a full tablespoon more than it should have. The smaller cups also held more than the measured amounts stamped on the handle.
When I tested other measuring cups for accuracy, I found only the four sets in the above photo actually measure the correct amounts. I wasn’t surprised to discover that all the cups I have been using for years were accurate, but many of the newer ones were not.
Use sugar to test the accuracy of a measuring cup for dry ingredients. One cup of sugar weighs 7 ounces.
Use water to test the accuracy of a measuring cup for wet ingredients. One cup of water weighs 8 ounces.
