Random one, Im cooking a Chicken for our Christmas lunch tomorrow. I normally use Bisto for gravy as Im quite a lazy/bad cook & time poor. This time I decided to buy a gravy pot ready made from M&S, as I imagine it will be much nicer than stock cubes. However I just realised I picked up Beef gravy! Can I still use it? Think it will taste okay with chicken? I cant get to the shops now.. x
