Consider investing in a few of the tools of our trade, such as a digital scale and a kitchen timer. A digital scale assures accuracy in the weighing of large ingredients like meat and fish and also helps to confirm volume measurements. A kitchen timer—inexpensive and easy to use—not only keeps you from scorching those crisp fried clams but helps to regulate cooking times, even when you get distracted.
Have on hand a trustworthy source for measurement conversions. A good one to use is www.onlineconversion.com, which can quickly convert a world of measurements, including volumes, weights, and temperatures. It will be worthwhile if you're working with recipes that originate outside of the United States.
Always use dry measuring cups for dry ingredients like flour and sugar and wet measuring cups for wet ingredients like tomato sauce and buttermilk. For accuracy, use a table knife to level off dry ingredients. Also remember that many of the measuring tools on the market today may look slick, but they're not always precise. For our money and time, we trust the old-fashioned, simply designed ones and leave the fancy versions to other cooks.
