enterprise’s kitchen. Common essences include anchovy, vanilla, peppermint and almond.

Ingredients used in stocks The three main ingredients used in the preparation of stocks are water, bones and vegetables. For chicken and beef stocks they are used in the ratio of 10 parts water:5 parts bones:1 part vegetables. Flavouring agents, such as bouquet garni, are also often used when making stocks.

Bones It is the bones in the stock that add most of the flavour. The gelatine in bones gives body to the stock. Bones are trimmed of excess fat and only washed if necessary to remove excess blood, as this can cause the stock to go cloudy. The most commonly used bones are beef, poultry and fish.

Vegetables Mirepoix (equal quantities of roughly cut carrots, onions and celery) is commonly used in stock production. These vegetables have a strong aroma and enhance flavour. Leeks are also sometimes used. In fish stock, onions are

Water In terms of quantity, water is the main ingredient used in stock production. Ensure the water used is clean and free of impurities.

Characteristics of stocks, glazes and essences A good quality stock should be clear, have a full-bodied flavour, be free from fat and impurities and have the appropriate colour and aroma. Meat and fish stocks should also be gelatinous. White stocks should have a light, clear colour and a dominant flavour of the type of bones used. Brown stock should have a clear, brown colour and a dominant flavour of beef and caramelised vegetables. A good quality glaze should have a syrupy consistency, a concentrated flavour, a glossy appearance, and be free from impurities and fat. A good quality essence should have a powerful flavour and aroma.

of stock are chicken, white beef, brown beef and fish. Vegetable and stock syrup are other common types of stock. All stocks are started by placing the ingredients in cold water, bringing it to the boil, then simmering it for a set amount of time. The stock is regularly skimmed to remove any impurities and then carefully strained and stored. Brown stocks are made by browning the bones and

Cooking times for stocks • chicken stock – 2 hours • white beef stock – 8 hours • brown beef stock – 6–8 hours

unit 4: prepare stocks, soups and sauces

Fish stock Fish stock is made from white flesh fish bones and trimmings. Oily fish, such as tuna and mullet, are too strong in flavour for a stock and will result in a bitter taste. Fish stock is quicker to cook than other stocks, as it doesn’t take as long to extract the flavour from the bones. First, melt butter in a stockpot and sweat sliced onions. Add fish bones.

or fruit/vegetable juice. Examples include vichyssoise and gazpacho.

Chowder Chowders are thick, hearty soups based on a thin velouté or béchamel sauce. Chunky ingredients such as corn, bacon, potato and seafood are folded into the sauce, which is then simmered. Examples include clam chowder, corn and bacon chowder, seafood chowder and potato chowder.

Garnishes, decorations and accompaniments Figure 4.03 A clear chicken and vegetable soup

Garnishes are an integral part of soups. They enhance the visual appeal and provide variety in texture and flavour. All garnishes used should be appropriate to the soup and cut small enough to fit onto a spoon. Suitable garnishes include herbs, cream, sour cream, and julienned vegetables and croutons.

Broth Broths are hearty soups with a high proportion of garnish. The main ingredients are stock, meat, fish or poultry and vegetables and/or cereal grains. Some broths will thicken slightly during the cooking process as the garnish swells or breaks down. Examples include minestrone, scotch broth and chicken broth.


Decorations include chopped parsley, grated parmesan and sour cream. Unlike garnishes, they are not an integral part of the soup and are only used to enhance presentation and visual appeal. Accompaniments are often served with soup to make the meal more substantial. A traditional accompaniment for soup is bread. Variations include crusty bread, bread rolls, toast, melba toast, damper, herb bread and croutons.

Puréed soups are thick and hearty textured soups.

creamy consistency. They are generally based on a béchamel or velouté sauce, and are finished with cream. The main ingredients are stock, roux and cream. Examples include cream of mushroom, cream of asparagus and cream of broccoli.

Bisque Bisques are thick, full-bodied soups made from seafood and fish stock. They may be thickened with a roux, cereal grains (such as rice) or a liaison. Examples include lobster bisque and prawn bisque.

Present and serve soups Portion control If soup is to be served as an entree, the serving size is approximately 200ml. For a main course, allow approximately 500ml per serve. This is a guide only: servings will vary in different establishments and often depend on the type of soup and accompaniments, if any, it is served with.

be produced to: pouring, coating and binding. The consistency will depend on the purpose for which the sauce is being used. • Pouring consistency – this is similar to that of single cream. The sauce will coat the back of a spoon and freely run off. Examples include jus lié, jus rôti and demi-glace. • Coating consistency – this is similar to thickened cream. Thicker than a pouring consistency, it should coat the back of a spoon. Examples include velouté,

béchamel and hollandaise. • Binding consistency – this is the thickest consistency. This sauce is used to bind ingredients together. The consistency is such that the sauce should stay on the back of a spoon when it is lifted out of the pan. Examples include panada and pie fillings.

Common problems and their remedies • Lack of flavour – may be due to insufficient cooking, a poor base stock or not enough ingredients in proportion to the liquid used. Remedies include reducing the sauce further or adding a meat glaze. • Starchy flavour – is generally due to insufficient cooking. The sauce should be simmered longer until the starchy flavour disappears. • Too thin - may be due to insufficient thickening agent or the reduction process not being completed. Remedies include re-thickening the sauce by whisking in a small amount of beurre manié (an uncooked paste of two parts flour to one part butter), bringing it to the boil and cooking for 5–15 minutes, or continuing to reduce the sauce. • Cloudy – may be the result of poor stock, insufficient cooking or puréed vegetable matter being in the sauce. Remedies include adding half as much good quality stock and reduce, continue to cook, or pass the sauce through a fine-mesh sieve. • Lack of colour – may be due to a poor stock colour or the base ingredients being incorrectly browned. Remedies include adding a meat glaze or adding well-browned mirepoix and/or bones and cooking for another 2 hours. Parisienne essence can also be used to improve the colour of a sauce. • Bitter flavour – may be due to the mirepoix, bones or sauce being burnt during preparation. Remedies include adding a little sugar, or if the flavour is not too strong, blending with a good quality sauce. If the flavour is very bitter, discard the sauce. • Lumps – may be the result of the liquid and thickening agent being mixed at too high a temperature. The remedy is to strain the sauce to remove lumps and continue cooking. • Split/separated – will occur if the temperature is incorrect (i.e. too hot or cold). This can be fixed by whisking a small quantity of the too hot or cold sauce with a little cold or hot water. If the sauce was too cold, do this over a hot water bath.

Prepare basic sauces Demi-glace Roast or fry beef bones to a medium brown colour. Add mirepoix and cook until dark brown, then add tomato paste and allow to brown slightly. Deglaze the pan with a small amount of beef stock. Add flour and cook until brown, stirring often. Add beef stock and seasoning (peppercorns, bay leaf, thyme and salt). Bring to the boil and simmer for 8 hours. Strain through a chinois.

unit 4: prepare stocks, soups and sauces

Béchamel Prepare a white roux (melt butter in a saucepan, mix in an equal quantity of flour and cook over low heat for a few minutes). Gradually add cold milk to the roux, mixing continuously with a whisk or wooden spoon. Continue to stir and heat the sauce until it simmers and thickens. Alternatively hot milk (that has often been infused with onion, cloves and bay leaves) can be added to a cold roux.

Chicken or fish veloute Chicken veloute is made using chicken stock, while fish veloute is made with fish stock. Both are made by adding stock (chicken or fish) to a blond roux and stirring continuously as the sauce comes to the boil and thickens.

Hollandaise or béarnaise Bring vinegar and peppercorns to the boil and simmer until they have reduced, then strain. Clarify butter and set aside. In a stainless steel bowl over a hot water bath, mix the reduction with egg yolks using a whisk. Gradually add the butter, whisking continuously. Temperature control is important with these sauces, too hot or cold and they will separate and curdle.

Mayonnaise Mix egg yolks, vinegar, Dijon mustard, salt and pepper thoroughly with a whisk. Add oil gradually, about 1 teaspoon at a time, whisking continuously. To help stabilise the mayonnaise, a little hot water may be added after the oil has been incorporated.

Jus Jus rôti is made by deglazing pan sediments with a stock appropriate to the meat being served. For example, a roast chicken pan would be deglazed with chicken stock, whilst roast beef would use beef stock. A jus lié is a jus rôti that has been thickened with cornflour.

Dessert sauces Coulis is a sweet or savoury sauce where the ingredients are puréed. Raspberry coulis is made by placing raspberries and stock syrup in a blender and puréeing. The sauce is strained through a fine strainer to create a smooth texture.

Thickening agents Through the process of reduction, liquids thicken naturally as water evaporates. However, it is generally necessary to add other ingredients to thicken sauces and soups. There is a range of thickening agents that can be used to thicken sauces and soups.

Beurre manié Beurre manié is an uncooked mixture of 2 parts butter to1 part flour. It is used to thicken sauces and soups at the last minute.

Cornflour, arrowroot or potato flour Cornflour or cornstarch is white flour made from maize. It is dissolved in cold liquid and then added to a hot sauce where it thickens at 85–96°C and creates an opaque finish. Arrowroot is a fine white flour made from a tuber (a native plant of the West Indies). Potato flour is extracted from dried, ground potatoes. Arrowroot and potato flour need to be dissolved in cold water and then thickened at 65–71°C.

Liaison or sabayon A liaison is a well-whisked mixture of egg yolks and cream that is used to slightly thicken sauces and soups. The egg yolks thicken by coagulation, which generally occurs at 80–88°C. Sabayon consists of egg yolk and a liquid that is thickened by emulsification. It is used in warm emulsion sauces and some desserts. Other thickening agents include modified starch and bread.

Store and reconstitute stocks, soups and sauces Stocks All stocks can be stored successfully in the refrigerator at 1–4°C for one week. They may also be frozen at -18°C for up to three months. When storing stocks, a cartouche can be used to stop foreign objects falling into the stock. It is important to cool the stock completely before storing. This is best achieved by placing the stock into small containers and stirring to reduce the heat evenly. The small containers can then be placed in ice or on a rack to allow air to circulate around them.

Soups Soups also need to be cooled before storage and should have any garnishes and decorations strained. Stored in the refrigerator at 1–4°C and covered with a cartouche, soups will last for up to three days. In the freezer at -18°C they will last for up to three months. When reconstituting frozen soups, they need to be thawed first to prevent the soup from scorching. It is advisable to add an appropriate liquid such as stock, water or milk when re-heating the soup to prevent it from catching on the pan and burning. All soups need to be brought back to boiling point when being reconstituted to kill any bacteria that may be present. Once the soup
