Have I mentioned I have an obsession with Pyrex prepware? No, then let me say, grew up with pyrex in the home, and you can't beat it for sturdiness, easy of cleaning, or sturdiness. This is one of several pyrex measuring cups I purchased when I rebooted my kitchen, to go with the bowls and bakeware. It can go from hot to cold and back again without breaking/cracking. I can melt butter in it on the stove, place on the cabinet, then continue to mix and measure with it - it doesn't add flavor (plasticizer) to the food, and is a dream to clean. This is the 1 cup measuring cup - I also have the 2-cup, 4-cup, and 8-cup. They are easily stored by nesting in one another, and measurement is precise. I'm looking forward to passing them on.
