Recipes are like song lyrics. You think you know them until the time comes to start singing. Where lyrics are concerned, you can just hum the melody and everything will probably work out OK. When you're dealing with a recipe, though, relying on your memory can spell disaster.
Drag out all your recipes, and review the ingredients again. Start a list of ingredients with quantities. Make this the year you don't have to send your significant other on an emergency store run for some sugar or a pound (or two) of butter.
Is this another year you're planning to make way more food than you'll ever need? Is it worth exhausting yourself for one more salad dish or dessert? Consider cutting back. You'll stay on budget and reduce waste, too.
