Stock, broth or bouillon is used as the basis for most soups, and in many dishes as a flavouring or base (e.g. risotto). Stock is made by cooking ingredients such as meat, poultry, fish or vegetables in water to flavor the water. The ingredients are removed at the end. Because the flavour of the ingredients is the only thing that matters, stock is often made with left over-ingredients and by-products such as bones, that couldn't be used elsewhere.

Stock can be made with a stock cube or extract, but for best results, make your own. If you cannot, a jar of fond (condensed stock) is the next best thing.

Vegetable StockEdit

This article starts with vegetable stock because most non-vegetarian stocks will use some amount of vegetables as well, to add depth to the flavor, so this information is useful for all stocks. Home-made vegetable stock will have a relatively weak flavor, but a strong aroma.

The basic ingredients for a vegetable stock are onion, carrot, leek, and celery. It is perfectly possible to make a good stock without any of these, but they are the classic 'backbone' of making stock and almost all vegetable stocks will contain at least two. Other ideas for vegetables are:

Keep the following in mind when choosing ingredients:

  • Do not use beet roots, because they will turn your stock black.

About 750 grams/26 ounces of vegetables per liter of stock should suffice.

To 'round off' the flavour of the stock some herbs and spices are usually added. Some of these will dissolve (like salt), for others it's best to create a little 'bag' - for example by wrapping the herbs in a leek-leaf with a bit of string - so you can easily fish them out later. Such a bag is called a 'bouquet garni'. Some good herbs to use are:

Preparing stock is as simple as putting the ingredients in a pot (preferably large and thick, like a Dutch oven). Pouring over cold water (it needs to be cold). Bringing the water to a simmer and waiting anywhere from 30 minutes to an hour, depending on how much stock you're making, and how strong you want it to be. Do not let vegetables simmer for more than an hour or the flavour will become wilted and sour. Some additional notes:

  • Do not chop your ingredients too finely. Just halve or quarter them, so the water can reach the inside of the vegetable as well as the outside.
  • Put the peels of onion and garlic in the stock as well. This will help with the color of the stock.
  • It's a very good idea, especially with vegetable stock, to caramelize your ingredients first. This can be done by pan frying them lightly in oil or butter, until they turn brown, but the oil will coat the ingredients, which will keep the water out and you'll have to defat the stock later to get the fat out again (if you want a perfect stock). The best way to caramelize your ingredients is to put them in the oven, on a tray, until they start to brown.

The stock should be tasted to see if it's ready. When it is, pass it through a sieve to get rid of the large ingredients. If the sieved stock isn't clear yet, put a wet tea towel in the sieve (or a cheesecloth if you have one) and pass the stock through it again. Instructions for clarifying the stock further and getting rid of the fat are given below.


Fish stock should generally be made using "white" fish bones like haddock, flounder, cod or snapper, although some Japanese recipes use tuna or similar species for a highly flavored specialized stock. Shellfish stock is generally made the same way as fish stock. Combine fish bones or shellfish shells with cold water to cover and add some diced mirepoix (carrots, celery and onion). Bring to a simmer, skimming as necessary and simmer for 40 minutes. Strain the stock and cool it. There are many options:

  • Sweat (cook in hot oil and/or butter without browning, often covered) the bones or shells and mirepoix before adding the cold water. This is called fish "fumet".
  • Replace part of the water with dry white wine or vintage dry cider.
  • Use white mirepoix (no carrots, add white part of leeks, mushroom trimmings and, optionally, parsnips)
  • Add aromatics such as herbs and spices (thyme, bay leaf, peppercorn, parsley stems). These may be added directly to the stock or tied in a cheesecloth (known as sachet d'épices). Add any other aromatics to impart a particular flavor.
  • Salt is usually necessary, add toward or at the end, to taste


Here's the basic method for chicken stock, which you can adapt for other poultry.

After you've eaten a chicken, don't throw away the carcass. Put it in a pressure cooker or a large saucepan, and add enough cold water to cover. Add some fresh herbs (basically, whatever is to hand, and whatever you like, but I tend to use bay leaves and sage, because they're always in the garden) maybe a roughly chopped onion, a carrot and a stick of celery, and bring to the boil. Pan drippings are very good to add, as long as they are not too burned.

If you use a pressure cooker cook at pressure for 30-40 minutes, in a saucepan let the stock simmer very gently for at least three hours (but no longer than four lest the bones cloud the stock and overpower the flavour). Drain the liquid through a sieve into another pan. You can use the stock immediately, or cool it as quickly as possible (stand the pan in a bowl of cold water) and refrigerate or freeze it.

A pressure cooker is ideal for stock making - the cooking time comes down from several hours to about 30-40 minutes, with considerable saving of time and energy (= less carbon emissions).


Beef, mutton and pork broths are made by slowly simmering meat (do not remove gristle - it contains collagen) with vegetables and flavourings. Do not add salt at this stage, it should only be added when the stock is being used in a recipe. Use cold water and warm slowly - this prevents the meat from sealing.

If bones are used in stock they may be roasted and cracked before simmering.

In a pressure cooker broth takes 45-60 minutes, stock with bones 75-120 minutes. If an open pan is used the liquid should barely be moving, and certainly not boiling fast, and times of several hours for broth and 7-10 hours for bone stock are not excessive.

Defatting and ClarifyingEdit

To get most of the fat out of a stock, you can simply chill it. The fat will harden and float on top of the stock where it can be scooped off easily. One can also use a fat separator, which is like a big measuring cup with a siphon from the bottom, which allows you to pour the stock out while trapping the fat.

To completely clarify stock, use the following method:

  • Beat egg whites to soft peaks, one for each quart/liter of stock.
  • Crumple the eggs-shells and mix them through the egg whites.
  • Stir the mixture in to the stock and bring it to a simmer, do not let it boil. The egg-whites will coagulate, rise, and take any particles and cloudiness out of the stock.
  • Keep a close eye on the simmer (push the coagulated egg-whites to the side a bit to see) and let it simmer for about ten minutes.
  • Remove the pot from the heat and let it sit for another ten minutes.
  • Finally, sieve the stock again through a tea towel.

Glace and ConsomméEdit

A glace is made by reducing a stock down (gently, stocks shouldn't boil) to about a quarter or less of its original volume. glace can be used as a basis for sauces, or simply to facilitate storage, and turned in to stock again by adding water.

A consommé is the result of the clarification process that uses egg whites and a fine dice of mirepoix to create a raft. this raft traps and removes impurities from a stock result in the classic clear quaity of a consommé


Stock will keep for about a week in the refrigerator. Frozen stock will keep for around six months.

Notes, Tips and VariationsEdit

  • A note on terminology: Stock is the result of cooking bones, or bones with meat, with water. Broth and Bouillon are the result of cooking any food-items with water to obtain a flavoured liquid. This distinction, however, is rarely made any more, and the terms are often used interchangeably.
  • Though mushrooms are good for enriching a stock, it is also possible to make the mushroom the main or even the only ingredient of a stock. For this you would need about 200 grams/0.4 lb of mushrooms and an onion per liter of stock.
