Inspired by my mom’s rectangular measuring spoons while I was cooking over Christmas vacation, I ordered my own pair and they arrived today. They’re Norpro brand, stainless steel with rubberized grips in standard 1 tablespoon and 1/8, 1/4, 1/2 and 1 teaspoon sizes, and I hadn’t seen them or other squared-off spoons elsewhere (Mom bought hers at an outlet mall), so I tracked them down on Amazon.com through a third-party seller.
These appeal to me because I can fit the spoons—even the tablespoon—directly into jars of spice for easy and accurate measuring. I also like that they increase my accuracy for eyeballing nonstandard measurements—half a tablespoon, for example, for which I can’t be bothered to remember or look-up the equivalent (1.5 teaspoons, in case you were wondering).
