I first came across bottles of concentrated stock when watching a Nigella Lawson programme. After trying it, I ditched the stock cubes and haven’t bought them since. Great for convenience when I haven’t got any stock left in the freezer or for when I don’t want much liquid in my dishes.
They have a strong flavour and add a good colour to a dish, as well as being versatile. They can be diluted to be as strong or as weak as you like, you can use them as seasoning, without any water, and to rub on for example some chicken with herbs and spices for extra flavour before cooking. Be careful not to use too much though as it can be salty.
Once opened, store your little bottle in the fridge.
As they say on TV, brands other than Knorr are available!
