Christmas is a great time to stock up on sale items to load the pantry or freezer. Look for great deals on items like sugar, flour, spices, butter, creamer, turkey, ham, nuts, etc.
Keep in mind that you can freeze dairy items - HOWEVER, the consistency will be slightly different when you thaw them. Cheese tends to be a bit crumbly (which is great for salads or melting), cream cheese can separate slightly (which when you whip it is fine), sour cream can appear curdled but the taste is fine (good for baking or other combined recipes), and even milk & creamer.
If you are a texture eater like me, make sure you have the right preparation for these products to enjoy your end results and make the most of your money savings.
