How To Use Dairy Products Correctly: Part One – Milk
Basic Preparation Of Foods: Dairy Produce.
These fairly basic tips may seem quite irrelevant to most modern householders who own a refrigerator, but modern technology do make people sloppy and so it is very worth while to know ‘why’ we ought do some things. For example, it is worth remembering these tips when your refrigerator is broken or is so small that it will not hold everything you have, such as when camping or boating or on holiday in some (parts of) countries in the world.
Milk has been called ‘nature’s perfect food’, because no other food, taken alone, can support adult life. It is of the first importance for the growth and development of young people, but it must be clean as bacteria also find it very nourishing and quickly multiply in it. If milk is not bought pasteurized, then it should be scalded and quickly cooled before consumption.
How To Scald Milk: Rinse out a clean pan with cold water, pour in the milk and heat until bubbles rise around the side of the pan. Maintain the milk at this temperature, ie, do not let it boil, for three minutes. Do not let it overheat, as milk burns very easily. Pour immediately into a clean receptacle and stand it in a basin of cold water and cover with a muslin cloth to discourage the ingress of flies and dust.
How To Keep Milk Fresh: If milk the is not be preserved in the receptacles in which you bought it, pour it into a clean container, which has been rinsed with cold water. A warm receptacle will cause the milk to stick to the sides and go off much more quickly. Always keep milk covered and in the coolest place in the larder. it is a good tip to remember that draughts usually occur at ground-level and that hot air rises. Never keep milk in an airless cupboard and in hot weather stand the milk in a container in a bowl of water with the cloth covering hanging in the water. The muslin will soak up water, which will evaporate, which dissipates the heat, ensuring that the container remains cool. Keep milk away from strong-smelling foods, as it absorbs smells easily. Never mix old and new milk together.
Sour Milk: Milk straight from the cow is slightly alkaline, but as it ages, lactic acid is formed and it becomes what we call ‘sour’. Pasteurizing or scalding the milk retards this process. Milk which is ‘on the turn’ can be rejuvenated by boiling with a pinch of bicarbonate of soda to restore its alkalinity. Once the milk has gone too far and has curdled, it can be strained through (cheese) cloth, thus separating the curds from the whey. The curds can be used as a filling for cakes, tarts, scones etc and the whey can be used as the liquid for making scones, cakes and soups etc., as it still has a lot of its goodness.
Evaporated Milk: Evaporated milk is ordinary milk, which has had some of its water evaporated by heat in some way or another before being containerised. Once reconstituted by adding water, it will last only a little longer than fresh milk does.
Condensed Milk: This is simply evaporated milk to which sugar has been added before canning. Sugar acts as a preservative and will keep the milk for about a week. Do not keep in the tin, but decant it into a jug or bottle.
Dried Milk: Dried milk comes in a variety of forms and notice should be taken of the instructions on the label. Specialized products can be bought for babies, invalids, convalescents and dieters, all of which contain varying amounts and types of added vitamins and minerals. Usually, they are very much lower in fat content than conventional milk.
