Don’t you go buying powdered sugar. Stick it to the man and make it yourself.
Here is how:
1cup and a half of plain granulated sugah
1tablespoon of corn starch
Stick that mix in a blender until it looks like powdered sugar. For me and my big-arse blender, that was under a minute. Let the dust settle and you will be well on your way to freedom. Freedom from people charging crazy prices for something so simple ( see vanilla extract ) makes me feel alive.
