In case you're ever jonesing for some nutrition information on that recipe you just made up, SparkRecipes has a sweet little calculator that allows you to plug in ingredients and amounts, determine the number of servings, and get yourself the nutrition info per serving. You have to register to save your recipes, but there's no reason you couldn't cut and paste the information and save it wherever you like. It's a handy little tool. Of course you may end up finding out that the Power Cookies you just made have 500 calories each, but you may choose to ignore that fact and carrying on eating them as before.
This calculator is exactly what I never knew I desperately needed. Thanks for posting it! :)
