My favorite kitchen tip is more of an aesthetic tip, rather than a cooking tip. Everyone has a kitchen sink, and everyone does dishes in their sink. Even if you are just rinsing them off to toss them in the dishwasher, you are going to need dish washing liquid. So you end up with your kitchen sink looking like this:See? So much nicer! A pretty glass bottle filled with bright soap (and dish soaps come in so many pretty colors these days, even clear so you can pick which ever color you like.) adds a little sparkle to my kitchen. Form and function! Just be sure to dilute the thick soap with water, so when you upend the soap, you don't stand around forever waiting for soap...
