If you're making several things at once, it might help to even put the items in separate work areas. Adapt any of these ideas to create the system that works for you. Keep a notepad in the kitchen to jot down your grocery list all week. As you run out of items, make a note on that pad immediately, when you recycle the empty container. When you go to the store, you'll know what you need.
Organization is just common sense, thinking through steps.
Organization will also help with one of the least-favorite kitchen tasks of all, cleaning. Although we know one guy who claims the state of his house is helping build up his immunity against germs, we don't recommend it. Chefs are taught to clean as you go, and you can train yourself to do this. Customize this idea to find something you can live with. Maybe you stack dishes in or beside the sink after you dirty them, and as soon as you come to a lull in the cooking process, you wash them all or put them in the dishwasher.
