Stocks and bouillons are the cornerstones of any good kitchen and should always be kept frozen. Is a rainy weekend on the horizon? Beef and chicken stock, a flavoursome fish or lobster stock will almost cook themselves in two days. You can find the basic ingredients in your delicatessa, bones, chicken, fish and lobster carcasses are available to order in advance. Then all you need is some root vegetables, plenty of water, patience and a large pot. This is also available at Globus.
