You're Spending Money on Ketchup
Making ketchup at home is extremely easy and, quite frankly, much better than anything you can get in the stores. Check out the Food Network's website for some guides on how to make your own red concoction today!
You Walk Away from Your Stove
Excluding crockpots, long simmered soups, and sometimes rice, you should always stand in front of your stove if it is on. A pot of water can quickly overboil while you're gone. This will get boiling water on the floor, possibly hurting you and anything/anyone else in your kitchen. That, and things can overcook in a heartbeat if you're not 100% attentive. Please stay focused for the duration that you're cooking.
