Flour is produced from different kinds of cereal and vegetables and used to various kinds of food.
The best example are chinese noodles that you can use in many types of instant soups and also sold as an ingredient of asian meals. They are made out of wheat flour with a relatively big amount of water what makes them soft by comparison to regular hard pasta that have to be boiled for at least several minutes. The instant soup with chinese noodles needs only to be poured over by hot water to be ready. You can also prepare the noodles on a frying pan with other ingredients of the meal to safe time.There also rice noodles and soybean noodles (that are accually made of mung beans flour). They have the same attribute – being easy to prepare just putting them into boiling water for some minutes.
Similar invention was developed in snack industry. There are companies that sell dry snack forms to the snack companies – see more snack pellets. So called snack pellets can be changed into ready to eat snacks that we can buy in a local shop. The process of turning a snackpellet into a ready snack is frying or baking. Baking is more healthful beacuse the snack contains in effect less fat, is lighter and has less calories. The flour used in snacks is mostly made of corn, potatoes, rice, wheat or mixes of some of them.
Flour is also used as a thickening agent in ready sauces, sandwich sauces, dips and salat dressings (like ketchup, garlic sauce, barbecue sauce, vinaigrette etc.). The flour used to thicken the sauce or soup is not a new idea. In old recipes it was often used, mainly the potato flour and starch. Potato starch is often called potato flour despite it is not exactly the same.The difference between flour and starch is how they are being made – the flour is made of boiled potatoes, the starch from raw ones – check snackpellets.
As we see, the flour is present in most of the ready meals that we prepare everyday. Also industry uses its advantage – it is easy to keep fresh for a long time when it is dry and it is also fast to prepare. Unfortunately it can be also a danger for our health because eating too much flour can cause obesity. So it is important to have a choice between fast and slow food and take time to cook for ourselves at least once a week.
