Today’s tool I can’t live without is:
|Odd Sized Measuring Cups|
These cups have been discontinued but another suggestion is here: Odd size measuring cups!
For me there are many times that you need 3/4 cup of something. Or even 2 cups of something. A set of odd size measuring cups includes: 2/3 cup, 3/4 cup, 1 1/2 cup, and 2 cups.
Not only do the cups make for easy measuring but also quicker clean up!
