Abstract
Oil or butter is introduced into a jacketed cooking vessel with a capacity of at least 300 litres, and is heated to a temperature of from 90{C to 95{C. Dry ingredients are added to the heated oil. The dry ingredients are sweated in the oil for a period of at least 3 minutes, until the temperature of the oil is from 50{C to 60{C. Cold water is added to the vessel in an amount of from 30 to 50 times the volume of cooking oil introduced into the vessel. The water is heated to a temperature of at least 90{C. A roux comprising about 50% by weight vegetable oil and 50% plain wheat flour is prepared. The roux is added to the heated mixture in an amount of from 10% to 20% by weight of the batch size. Vegetable pieces are added to the thickened mixture in the vessel and the vegetables are cooked over a vegetable cooking time of typically 30 minutes. There may be a number of different vegetables added which may be introduced at different stages. For example, carrot pieces may be introduced first followed 10 minutes later by mushrooms and followed a further 10 minutes later by peppers. Water is intermittently added to the mixture in a total amount of from 1% to 10% of the batch size during only the first 60% of the vegetable cooking time. The cooled mixture is packaged in pouches of a suitable size for cooking/reheating by the customer. Further food pieces such as meat pieces may be added to the pouch.

Detailed Description
In the invention a cooking vessel having a capacity to produce a batch size of at least 300 litres, usually up to 450 litres is used. The vessel is a jacketed and agitated stainless steel cooking vessel which also has an emulsifier fitted. The system used also comprises a vacuum cooler with a transfer pipe from the cooking vessel.
Oil or butter in an amount of about 2 kgs to 3 kgs is introduced into the cooking vessel. The oil is heated to a temperature of from 90 C to 95 C by circulating steam through the vessel jacket. Dry ingredients such as seasonings, herbs, white wine, and/or garlic are added to the heated oil. This addition causes the oil to cool and the dry ingredients are sweated in the oil for a period of at least 3 minutes, generally about 5 minutes, until the temperature of the oil is from 50 C to 60 C.
Prepared fresh onion pieces are then added to the sweated dry ingredients and the mixture thus formed is sweated for at least a further 5 minutes, generally about 10 minutes.
Cold water is added to the vessel in an amount of from 30 to 50 times the volume of cooking oil introduced into the vessel. The water is heated to a temperature of at least 90 C.
A roux comprising about 50% by weight vegetable oil and 50% plain wheat flour is prepared. The roux is added to the heated mixture in an amount of from 10% to 20% by weight of the batch size. An average of 30kg of roux is added. The range is between 25 and 40 kgs of roux, depending on the moisture content of the vegetables.
Additional natural ingredients such as cream or sometimes wine may be added with the roux.
c: .. Be: e. :. . : Fresh vegetables are prepared, for example, by cleaning, skin removal and cutting to size. The vegetable pieces are added to the thickened mixture in the vessel and the vegetables are cooked over a vegetable cooking time of typically 30 minutes. There may be a number of different vegetables added which may be introduced at different stages. For example, carrot pieces may be introduced first followed 10 minutes later by mushrooms and followed a further 10 minutes later by peppers.
Water is intermittently added to the mixture in a total amount of from 1% to 10% of the batch size during only the first 60% of the vegetable cooking time. This counteracts evaporation losses but without sacrificing quality and flavour. The amount of additional water added in this period is determined based on seasonality factors and vegetable moisture content. Additional roux may be added during this intermittent water addition phase.
During the sweating and cooking the contents of the vessel are continuously agitated.
The mixture may also be emulsified for particle attrition at the dry ingredients addition stage, the onion addition stage, the roux addition stage and/or when additional vegetables are added.
After cooking, the contents of the vessel are transferred to a vacuum cooler in which the mixture is cooled to a temperature of less than 5 C. To optimise capacity usage cold water may be circulated through the jacket of the cooking vessel prior to transfer of the mixture to the vacuum cooler.
The cooled mixture is packaged in pouches of a suitable size for cooking/reheating by the customer. Further food pieces may be added to the pouch. Such food pieces may be white meat such as chicken pieces, red meat pieces or fish pieces. The additional food pieces are first seasoned and the exposed surfaces of the pieces are sealed in a heated pan. In the case of chicken pieces the pan is heated to about 320 C and the chicken pieces are sealed for about 40 seconds. In the case of red : . : A: . : :e meat pieces the pan is heated to about 350 C and sealed for about 30 seconds. In the case of fish pieces, the pan is heated to about 300 C and the fish pieces are sealed for about 25 to 40 seconds.
The sealed ingredient pieces are placed on a cooking rack and blast chilling of the sealed ingredient pieces is commenced about 30 seconds after removal from the heated pan.
The blast chilled meat pieces are added to the pouch.
Example
A batch of 350kg of chicken curry is prepared as follows.
3.5kgs of butter is added to the cooking vessel as described above. The butter is heated to a temperature of from 90 to 95 C. Dry ingredients comprising 4.343kg of mild curry paste, 10kg of chopped tomatoes, 0.280kg of cinnamon, 0.200kg of coriander, 0.140kg of Masala, 5.2kg of sugar, 0. 608kg garlic puree and 5.2kg of chicken bullion are added to heated butter. The ingredients are sweated to a temperature of about 40 C for about 2 to 3 minutes.
litres of cold water are added to the cooking vessel and the mixture is heated - 40kg of a roux comprising 50% vegetable oil and 50% cream flour is added to the water mixture. 1.107kgs of tumeric is added after the roux. The mixture is emulsified for about 20 minutes. 17kg of cream are added and the mixture is further emulsified for another 2-3minutes, maintaining the temperature at 90 to 95 C. 0.1919kg of salt and 0.069kg of pepper are than added.
:.. ce. e' e. a' Additional vegetable pieces are then added to the thickened mixture. 40kg of chopped carrots are added and cooking continues for 5-10 minutes. 30kg of mushrooms are then added and cooking is continued for 2-3minutes. At that stage 40kg of onions, 10kg of red peppers and lOkg of green peppers are added. is
During the first 60% of the vegetable cooking time between 5 and 12kgs of water are added intermittently depending on the moisture content of the vegetables and the texture of the sauce. Cooking is continued for a further period of about 20 minutes.
The mixture thus prepared is transferred to the vacuum cooler where it is cooled to about 4 C prior to packing into appropriately sized pouches.
lkg whole chicken breast meat is sealed on a pan which is preheated to about 320 C.
All sides of the chicken breast are sealed over a period of about 40 seconds. The sealed whole breast is then cut into cubes of about 20x20x20mm. The chicken pieces are laid on a pack and blast chilling commences not less than 30 seconds after removal from the pan.
The cooked chicken pieces are loaded into the pouches. The pouches are then sealed and the contents are frozen in a spiral freezer.
A range of high quality meals may be prepared in this way. The meals may be supplied frozen in vacuum-packed pouches. When defrosted, at the point of use/sale the meals may be proportioned into individual microwaveable trays. When required, the food may be heated in a microwave ready for immediate consumption.
Alternatively, the food may be heated directly whilst still in the pouch, either in an oven or by immersing in hot water and boiling. A steam oven at 100 C or a convection oven at 150 C may be used. In the case of a convection oven a bowl of water may be added to create steam.
