A réchauffé dish is a reheated dish made from leftovers from previously cooked food. Classic examples are Cottage and Shepherd’s Pies where minced cooked meat would be cooked with onions, carrots, and gravy, topped with mashed potatoes and baked. It is thought that the origins of the popularity of American-Chinese Chow Mein was as a way of using up precooked meats and noodles.
Wok hei, means ‘the breath of the wok,’ it is the smoky flavours, aroma and texture the dish picks up whilst being stir-fried in a hot wok. It is particularly prevalent in Cantonese cooking. To impart wok hei the traditional way, the food is cooked in a seasoned traditional cast iron wok over a very high flame while being stirred and tossed quickly. The heat needs to be extremely high to stop the food being boiling in its own juices and being stewed. When you see professional Chinese chefs cooking over gas stoves or an open flame, they toss the food at an angle allowing for the splattering of fine oil particles to catch the flame into the wok adding more Wok hei.
Thickening sauces have developed from using starchy vegetables, the ground nuts, and breadcrumbs from medieval cookery to using gums and gelling agents in today’s advanced gastronomy. The most common and popular methods are;
This is a French term meaning to finish a sauce with butter forming an emulsion. Immediately before serving you can whisk in chunks of cold unsalted butter, one at a time, into a hot sauce. The sauce must not boil or the butter emulsion will split. The finished sauce has a velvety texture and rich flavour.
Is a paste made by kneading butter and flour together which can be crumbled over and quickly whisked into a simmering sauce. It can be made in advance and stored in the refrigerator. A ratio of fifty grammes of butter to seventy-five grammes of plain flour will thicken one litre of sauce.
This is a mixture of cream and egg yolks, used to thicken soups and sauces. Never add directly to hot liquids or the eggs will cook out and scramble. Temper the liaison by adding a small amount of the hot sauce to it which gradually raises the temperature, then whisk this mixture back into the remaining sauce. DO NOT BOIL and serve straight away. This is a very rich method of finishing classic sauces.
A slurry is a mixture of a starch and cold water. You can use cornstarch for thickening milk or dairy sauces, arrowroot used to thicken fruits juices because of the clear, glossy finished result on fruit tarts, potato starch, rice flour, wheat flour or dried powdered yam. The ration is one-part starch with two parts cold water. Always remove the sauce from the heat before adding the slurry to stop the starch cooking in thin streams or ribbons and not mixing. Then return to the heat stirring continuously.
Tomato concassé is the flesh from fresh tomatoes that have been peeled, de-seeded and chopped into a dice. It is a staple of many professional kitchens used in sauces, omelettes, with olive oil, garlic, and basil as a topping for bruschetta and when added to Béarnaise sauce to make Choron sauce, served with fish and seafood. We remove tomato seeds and skin from Tomato concassé asin large quantities they can be tough, do not soften during cooking and leave a bitter flavour. If you can get hold of a moderate amount of ice it is very useful when cooling off the blanched tomatoes. Use fully ripe but firm tomatoes for the best results. The process may seem to be quite an effort but the end results for Tomato concassé are very pleasing and worthwhile.
To make tomato concassé
Bring a large pot of water, deep enough to generously cover your tomatoes, to a rolling boil.Take each tomato and using the tip of a small sharp knife or paring knife ( see picture ) remove the pith or tough part of the tomato where the stem used to be cutting out a circular hole.
Turn the tomato over and on the other end mark a small cross in the skin with the knife.
When all your tomatoes are prepared, place a four or five at a time into the pan the boiling water. As soon as the water returns to a boil cook for one-minute longer and then remove them using a slotted spoon or spider.
Immediately plunge the blanched tomatoes into a large bowl of very cold water to arrest the cooking process. If you have ice, use iced water. The cooking process depends on the size of tomatoes you are using, small tomatoes may only require thirty seconds simmering. A good rule of thumb is if you see the tomato skin beginning to peel off then take out and cool.
The next step will take a little practice. Drain the blanched tomatoes then using the sharp knife again gentle tease and peel off the skin. Start by slowly sliding the tip of the knife under the cross you made in the skin earlier and work down. When peeled quarter the tomatoes and remove the seed with a small spoon or the back of the knife. Chop the quartered tomatoes into large or small dice as required.
A roux is a mixture of flour and fat used to thicken sauces, soups, and stews. It is traditionally used to thicken the classical French Béchamel, Velouté, and Espagnole sauces and in Cajun and Creole cooking. The roux is made from equal parts wheat flour and either butter, vegetable oil, bacon drippings or lard which are cooked together with or without colouring. In Cajun cuisine, the roux is almost always made with oil or lard instead of butter, which would burn and is dark brown in colour, adding greatly to the flavour of the finished sauce. In regional American cuisine, bacon is sometimes rendered to produce the fat to use in a roux for extra flavour, in recipes such a sausage gravy. In the case of meat gravies, fat rendered from meat is often used to make a pan gravy.
Cooking the roux produces the correct chemical structure to thicken the sauce and starts to remove the floury taste from the finished sauce. A light roux of flour and butter, cooked for two or three minutes without colouring is used in the traditional béchamel sauce. Cooking until the mixture becomes golden in colour and sandy in texture produces a blonde roux the base of velouté sauces. Darker roux can range from light brown to chocolate in colour and add a distinct nutty flavour to a dish. The darker the roux, the less thickening power it has, a chocolate roux has about a quarter of the thickening power, by weight, of a white roux.
The golden rules when thickening a roux based sauce is to allow the roux to cool slightly after cooking and use a liquid that is just off the boil to make combining the ingredients much easier. The sauce will then need to very gently simmer for at least thirty minutes to cook out and eliminate any floury taste. The resulting sauce will be smooth, rich and creamy in texture.
Classic Espagnole or Brown sauce is a dark, flour-based sauce with a strong taste and is now replaced in many recipes by a well-reduced beef or roast veal bone stock, traditionally it was a Master Sauce serving as the starting point for many derivative sauces, of which there are hundreds in the French repertoire. As Espagnole is the French word for Spanish it was long thought that the sauce was a creation of a chef to one of the two countries royal courts following a diplomatic marriage between the French and Spanish thrones, similarly, Espagnole was a rich marriage of Spanish tomatoes to a traditional French brown meat sauce. However, according to Alan Davidson, in The Oxford Companion to Food, “The name has nothing to do with Spain, any more than the counterpart term allemande has anything to do with Germany. It is generally believed that the terms were chosen because in French eyes Germans are blond and Spaniards are brown.”
As Espangole was a staple of the large classical kitchen the ingredient list includes parsley stems and mushroom trimmings left over from the preparation of garnishes, these are optional or simply replace with a couple of sprigs of parsley and a few mushrooms.
Roast the trotter and beef shin in a very hot oven for twenty minutes until brown. In a very large, heavy bottomed pan melt the butter and fry the bacon, add the mirepoix of root vegetables and cook slowly. Brown the vegetables so the natural sugars caramelise to add flavour and colour to the sauce. Add the flour and cook for at least another five minutes to develop the colour.
Slowly add a quarter of the stock stirring all the time then add the remaining stock, trotter, beef shin and the rest of the ingredients. Bring up to the gentlest of simmers and cook for at least three hours. Skim regularly to remove any impurities and excess fat from the sauce which if let to boil into the sauce will result in a cloudy finish. Remove from heat, allow to cool and pass through a chinois or fine sieve.
Ghee is a south Asian pure butterfat used for frying and flavouring similar to clarified butter. The production of ghee results in the elimination of any milk solids which prevents the ghee from oxidising, consequently ghee has a long shelf life and does not require refrigeration. Ghee is commonly used in Indian, Bangladeshi, Nepalese and Pakistani cooking. In Indian cookery, ghee is used in the preparation of dishes such as biryanis, daals, parathas and curries resulting in a rich flavour and texture and is brushed on roasting Naan breads. The word ghee comes from Sanskrit.
Commercially prepared ghee is made by first melting the butter, as it does the milk solids and buttermilk form a white froth on top. This is removed and the butterfat is then simmered, stirring occasionally, as it is cooked on low heat it turns a dark golden colour. Any remaining residue settles at the bottom and the ghee, which is now clear, aromatic and golden is ready to be filtered. The ghee solidifies as it cools. The texture, colour, and taste of ghee is altered by the length of the cooking process and from the milk which made the butter.
Ghee is an ideal medium for deep fat frying because the smoke point (where it begins to break down) is 250 °C / 482 °F, which is well above typical cooking temperatures for most foods around 200 °C / 392 °F and above that of most vegetable oils. Several other cuisines produce similar products to Ghee. In North Africa, the Berber tribes add spices and age their refined butter. In other parts of Africa purified butterfat is used for frying and in Germany Schnitzels are traditionally fried in Butterschmalz a type of clarified butter.
