Proper measuring equipment is useful for following recipes and monitoring portion sizes. Check you have dry and liquid measuring cups, measuring spoons, pitchers and scales.
A fat separator is an excellent tool, especially during the holidays when you might be making lots of gravy. This takes the work out of straining fats from liquids.
A blender and food processor are excellent tools to have generally, and helpful in pureeing fruit and vegetables to help thicken soups and sauces.
Use your microwave oven. It's another useful tool for cooking food fast while preserving nutrients. It basically steams the food.
Make good use of your oven: broil, bake and roast your meat and vegetables, since the fat will drip away from the cooking racks.
